[Editor] Support a wider range of colors (especially skin tones)

[lewxdev]

I understand the original artists may have a recommended or original color palette, but I've found some of the choices limiting, especially when it comes to skin tones.

I propose, in addition to the existing individual colors, provide an optional slider of gradient colors to improve the customization

I think apple's Memoji editor handles this well, providing both individual colors and the spectrum they fall on

Hi @lewxdev

I like the idea. I'll see what I can do.

actually I already did it ... for myself
just use the <ngx-colors/> and wider skin palette
