The fountain-on-a-fire is found in the top left of Aguascalientes' coat of arms, and represents the state's hot waters, after which it was named.
Campeche's current coat of arms is quartered, with two parts blue with a ship, and the other two red with a castle. The wavy stripe from the shown first proposal references both seaports (the ships in the arms), and snakes (from which the ). A second flag includes one castle and one ship on a quartered background.
A simplified rendition of the state's , depicting the river running through the , charged with the palm tree and lion. Though the color of the cliffs varies between versions of the shield, and it is actually sinople (green) in the , I've kept the Wikimedia version's brown as it is so rarely used as a major color on flags.
Like the coat of arms on the current flag, this proposal for Chihuahua has a sky blue background with sixteen red and white squares, which in the original represent the for and against votes for the creation of the (the city and state arms are identical). In the center of the flag is the apple tree flower that appears in the corners of the state coat of arms.
Based on two own modifications of a design by Daniel Martínez Miranda, which has a white cross with the squares in two of the quarters, this second proposal adds a flower in each of the remaining quarters.
Coahuila and Guerrero
The November 2017 edititon of /r/vexillology's monthly contest concerned Mexican states. Since submissions have to be newly designed, I made flags for two states I hadn't covered before. Neither design made the top 20, although the one for Coahuila was mentioned in the results thread as the highest-voted design for its state, coming 71st overall.
The lower half of the state coat of arms shows some trees along a river, representing the foundation of former capital Monclova, and a sun for the Mexican Revolution, all kept but simplified in the hoist of this flag. The upper two segments of the coat of arms reference two Spanish areas that parts of the state were named after, and , now represented by the tree and the green-white-black color scheme. The layout alludes to the flag of the short-lived , which included Coahuila.
The colors, triangular dents and(a wooden weapon with sharp blades on its sides) are from the . The diagonal design is a reference to the the state's namesake, , was part of; also, the choice of a weapon as central charge reflects the name "Guerrero" meaning "warrior").
#2 is an unsubmitted alternate version with a red background; the newer #3 replaces the macuahuitl with the green and yellow pattern from the arms.
The coat of arms of Colima features a hieroglyph for an arm, representing volcanoes, which I've kept. The yellow and white stripes, modeled after the , are from a government proposal; the red border is from the current coat of arms.
The scorpion (this specific image of which is admittedly a little cartoony) is a popular symbol for the state of Durango. The colors of the first flag reference those of both the current flag and the arms of Durango's ; the second uses an unofficial flag consisting of a white saltire on a green field as background.
The cross and Guanajuato's coat of arms. The frog represents the possible original meaning of the state's name in ("place of frogs"). #2 is based on an unofficial flag, using a yellow diagonal cross on a blue and green field.are the items held by Santa Fe de la Granada on
Hidalgo's coat of arms contains several references to its namesake, Mexican independentist leader : the bell in the top left represents his of the war for independence from Spain in 1810, and behind the shield is the Mexican flag as well as a blue flag depicting the that was used by him. This redesign features the bell on a bicolor of blue and green, based on the coat of arms.
After Miguel Hidalgo's execution by the Spanish in 1811, a maroon flag with black cross was flown in his honor in several battles of the Independence War. These flags combine it with the blue field of the Guadalupe flag and the pickaxe-pyramid-bell symbol of Kyrgyzzephyr's proposal.
These designs are inspired by the Virgin of Guadalupe herself, as she is usually depicted wearing a cerulean mantle with golden stars, standing on a dark silver crescent held up by an angel. The vertical triband design of #6 is based on the national flag.
Jalisco and Tlaxcala
The flags of Jalisco and Tlaxcala are the only Mexican state flags to not have a solid white background; they are a blue-yellow vertical bicolor and a red-white diagonal bicolor respectively. They do, however, like the others, include the state coat of arms in the center. My redesigns replace the coats of arms with their main symbols: for Tlaxcala, the Castilian castle, and for Jalisco, two lions and a tree.
The top sections of the coat of arms of Mexico State include the and a scene representing the , which I've combined. The colors are those of the national flag, symbolizing the homonymy of the state and the country.
Two versions of a banner-of-arms with stylized castle and bridges, the first of which removes the border of cactuses.
These flags instead focus on the arms' foundation of the Aztec city-state of , located where Mexico City is now.cactus, as it is its only explicitly local symbol (other than the blue background for ); the coat of arms as a whole has caused as some see it as a Spanish imposition. The prickly pear is also another link with the national symbols: the eagle in the perches on one, representing the
Inspired by (and based on) Ricardo Vazoli's design, #6 adds the Aztec symbol of the island of Tenochtitlan, which is also included on the national coat of arms. The flag's prickly pear has ten red flowers, nodding to the city arms' ten cactus leaves.
These proposals for Michoacán are based on the fish and hill from the crest of the state coat of arms, which are the Aztec glyphs for the state name. The backgrounds reflect the state colors of red and yellow, which are also the main colors of the coat of arms.
All of these flags use only elements from the coat of arms of Nayarit. The first is a local proposal charged with the corn plant, eagle of Aztlan and bow and arrow from the arms (the graphics being based on Sotajarocho's proposal). The second is a red-yellow bicolor, based on the coat of arms, charged with the same eagle drawing. The third through fifth have the bow and arrow and eagle on a red or red-yellow background.
Besides the purple lion of the state's namesake, the , the first three of these proposals use the chain from the central shield of Nuevo León's coat of arms, which represents unity as well as the , after whom the capital was named.
All three differing only in color scheme, the first is color-inverted compared to the symbols of León, symbolizing the "new" part of the state name (see New Hampshire #2 and #3), while the second uses the original colors of both the lion (purple on white, disregarding the tongue/nail and crown color) and the chain (black on white). The third uses the blue and yellow from an unofficial flag.
Similarly to the design for Coahuila above, the fourth design is based on the , combining the local yellow and blue with the Leonese purple.
This is basically a banner of arms, with the red and blue squares moved to the hoist. All elements of the coat of arms of Quintana Roo except the sun are included.
San Luis Potosí
These redesigns for San Luis Potosí combine symbols of the state's two namesakes: the quartering from the flag of , Bolivia, and a fleur-de-lis for French king (who is pictured in the state coat of arms). The pill shapes/rectangles (which represent gold and silver mining) and colors are from the coat of arms.
The coat of arms of Sinaloa is modeled after the , which grows in the state and is also the origin of its name. Flags 1 and 4 consist of a dragonfruit (and like Durango's scorpion could use a better image of it) on a yellow-green bicolor. #2 uses a more stylized but less recognizable version of the fruit; #3 depicts its white interior and has 18 black seeds representing the state's municipalities. #4 and #5 use four stars referencing the four cities represented in the quarters of the coat of arms.
The colors and field division are hased on Sonora's coat of arms. The top section of the arms depicts the of the local tribe, which is represented in my first proposal by the dancer's deer hat, and in the second by a deer's head.
Inspired by Superham1's proposal, both designs originally included a red seven-pointed star between the antlers, taken from the flag of the short-lived ; I removed it after reading more about this former unrecognized country, which as I read it was a private colonization attempt by an American, and hence quite a weird thing for a new state flag to refer to. (I originally assumed it to be a breakaway state like the or ; the references to these in some of my other state flags may well be equally unwarranted, although the independentist at least seems to still have some use as a symbol of local pride.)
One of Tabasco's existing unofficial flags is quartered red and white with a counterchanged cross (similar to MetamarioMX's proposal). This flag combines it with the red and bluish silver quartering of the current coat of arms.
These proposals for Veracruz retain the red cross (a on the state's name, which means "True Cross") and the . The first uses a blue background; the second is based on a version of the current flag that includes a red and green border.
In the 1840s, Yucatán was , with a flag consisting of red-white-red stripes, a green hoist stripe and five stars. The current de facto flag, however, is simply a white bedsheet with the state coat of arms, no different from most other states. My proposal combines the two, using the field divisions from the former flag and the colors and deer from the state flag.
