The blue is kind of close to what I'm using for the MC, but we'll try that and see how it goes. I did a quick test and they're different enough that I think it works. Purple and gold are great suggestions but I'm using purples for Sara and Izzi, and Xiang is going to get gold.
Glad to help when/if I can. To figure any of them out, and to get a complimentary palette, I just pull up a hex code site that lets me choose by code or base colors. Then once I've narrowed down the color I'm looking for, it gives me complimentary colors that fit within a palette I can choose.
That's where those secondary colors came from, and why they look good together.
My mother worked in cosmetics and skin care for many years, so that among other things has given me some insight into color palettes, finding the right hue, and matching.
Can certainly be fun, and time consuming if you head too far down the rabbit hole
