Is there a way to change the color of player controlled generic mimes? For example, change player mimes to use their #5 palette (sort of a purple-ish blue). I tried reading posts about custom palettes for hours, but couldn't figure this one out.
Yes, but to get it to show outside of battle requires a bit more work than most people are willing to do. Changing the in-battle sprites to another color is a quick export with Shishi, then load the palettes you want into the exported BMP from itself copying palette 5 over 1, and 1 over 5 and the same with palettes 9 and 13 for the portraits, and reimporting that BMP back into the ISO with Shishi.
Also, Get Xifanie's pallette editor. I reccomend it as the best possible way to change colors.

Thanks for the help, Xifanie's program definitely helped a lot on changing the battle palette. As to changing the formation palette, I don't know what method you were going to suggest, but I didn't find this to be much work or difficulty at all, so I'll go ahead and post what I did just in case:
Use FFTEVGRP to open UNIT.BIN and go to the sprite you want to change the palette of. Save the palette (PAL file). Open it in a hex editor and starting at location 0x16 you're looking at the RGB values for each of the 16 colors in sequence (separated by a byte '00'). Now just take whatever value you used in Xifanie's program for that color and multiply by 8, then convert to hex. Pop em all in, re-import the palette in FFTEVGRP, and voila. Your formation sprite now has the same palette as the battle sprite.
