Like I said, this is the animated version of Rainbow Dash's Emblem. It didn't come out as well as I wanted it to, the fading effect on the trail for some reason did not want to work, going to see if there is anything I can do about it.
That is what I thought you meant if you did not mean actually make them in solid form. I had not thought about it, but I might, if I have some free...creativity you may say...I have several things that I need/want to work on at the moment :/
The reason the trails did not work is the fact that they are dithered due to GIFs being restricted to 256 colors. If you could try making an APNG (Animated PNG) it would have the trail in a beautiful 16*10^6 (and more) colors.
