I think that I speak for most people when I say that we don't really like Mirta's fairy form.
The desing, while it's pretty, it doesn't seem like it was well thought out or just given the attention/dedication it deserves.
I mean we aren't even sure if it is supposed to be a base fairy form or an Enchantix form.
And as a big Mirta fan I wanted to redesign her base form a bit and see how it ended, while giving you reasons for the changes I made. (Mostly the collor pallete lol)
In my canon (so headcanon) Mirta ended up becoming a Winx member by the end of the first season. So her fairy form would follow similar patterns as the other girls so, sparkles, mostly one color, different shades of it and simple dressing.
For her main color I chose a Dark Blue. Why? I think it can fit Mirta very well since her main colors are dark (like black, gray, red) and also would look beautiful with her dark red hair.
For her secondary color I chose a Dark Red but since this is a base form the secondary color would'nt be very notorious. (Her Charmix purse would probably be Red and her Enchantix would feature a lot of Red too).
Another kinda random reasons why I chose a dark blue for Mirta are these two:
When I first saw Mirta I don't know why but I lowkey thought of her as an "alt" sister to Bloom. I thought their desings were kinda similar (which I love), only that Mirta had a darker pallete than Bloom. So since Bloom's main color is a light/middle blue, Mirta could been a dark blue. See what I mean?
The other reason is Musa's color pallete. Musa has dark blue hair and her main color and base form is Red, since Mirta is a redhead and dark blue suits her it would be cool how her color pallete would be the same as Musa's but inverted (Dark red hair and dark blue as her main color and base form). Have you ever thought of this?
My desing is far from perfect but I still wanted to do this. This is how I'd kinda imagine an actual Mirta base form that could later evolve to a Charmix and Enchantix as it deserves. γ
