Edit: Sorry if this is outdated, but I had forgotten about it until somebody pinged me. I'll update with new colors from the color wheel soon.
Every deity has a different profile image because they're a different "breed". The thing is, their listed colors (which have no genes) don't match the colors in their profile picture. They're all wrong. Check this out:
Eartshaker, stone/slate/brown. His primary seems to be stone, and the slate seems to be his back, but is his beard supposed to be brown? It isn't. I guess maybe his aura is brownish.
What it should be:
Stone/slate/soil. Just a little change that matches the eyes and the aura better. The dragon gods all have auras of their flight's eye color.
Flamecaller, fire/maroon/red. Her primary isn't even fire, and I guess it can be considered a maroon, but it seems more like a dark brown to me. I don't see where plain, crayon-red comes into her design either.
What it should be:
Slate/maroon/sunshine. Colors are an approximation though, since she has colors that we can't use.
Windsinger, seafoam/spring/aqua. I'm not seeing spring on him anywhere. He's definitely seafoam, and his wind swirly things are aqua, but the only other color I'm spotting on there is his spines, and they look more like jungle. He has other greens on him, but nothing on our color wheel.
What it should be:
Seafoam/jungle/aqua. It could be Seafoam/aqua/jungle spines if you're making a dragon based off of him, though.
Tidelord. He always looks so happy. Bubbles, yay! Blue/aqua/caribbean. He does seem blue (more of a cornflower blue though) but that's about it that matches. His secondary looks more like teal on the inside of the wings, and there's no caribbean on him....unless you count his bubbles.
What it should be:
Blue/navy/splash. Going with the outside of the wings on secondary.
Shadowbinder, shadow/black/violet. That gloomy aura is violet, so that's correct...but her primary isn't shadow. Her secondary could be considered shadow, at least where we can see the translucency of her wings, but otherwise I'd say it's midnight. Her primary isn't black, it's more charcoal or grey.
What it should be:
Charcoal/midnight/violet
Icewarden, ice/sky/white. At least ice is actually his primary. It seems a lot of deities have the color that represents their element, even if it's not part of their actual color scheme. Sky works well enough for his clumps of ice, but there's no white on him. Splash or even blue works better.
What it should be:
Ice/sky/stonewash. He has a big gradient on his blue parts that goes from ice to blue, so stonewash is kind of in the middle.
Stormcatcher, obsidian/aqua/teal. Neat colors, and nothing like him. His little zappy pattern (his tert?) is aqua, as is his godly aura, but that's about where the similarity ends. If anything I'd say his colors are the same as Shadowbinder's, except there's aqua instead of violet. Tight range, would breed.
What it should be:
Charcoal/midnight/aqua. His aura is actually cyan, but that's not an available color on FR's color wheel.
Good ol' glittermom. Lightweaver, sunshine/banana/gold, and the deity that made me think about how wrong these colors are. There isn't sunshine on her anywhere, so it's another "this is my element so this is the color I'll be listed as". There's no gold either. Banana? Sure. But otherwise the glitter lady is goldenrod.
What it should be:
Goldenrod/banana/ivory. I know her aura is banana, but she has ivory on the inside of her wings.
Gladekeeper, jungle/forest/green. Her leaves are green, and her body is forest, but there's no jungle there anywhere. It's a shame because jungle's a nice color.
What it should be:
Forest/green/green, although the leaves on her are somewhere between green and emerald.
Plaguebringer, blood/maroon/red. She's almost the same as Flamebringer. Her aura is red, her body is maroon, and there's no blood on her anywhere. The color, I mean.
What it should be:
Maroon/soil/crimson
Arcanist, pink/mulberry/white. Not even close. That's okay, Arcanist. You tried.
What it should be:
Lavender/violet/magenta. Still not completely correct since there's no pale purple like his primary, but close enough.
Anyway I wouldn't want to change the colors they all have, but it's kind of interesting to see how much they don't match the official artwork.
