like eg: pink, blue, etc? Cuz I tried the application for the sprite customisation and it only has light to dark shades(skin colors) not like pink, etc so like if I want to add any colour of my choice how can I do it? Sorry I’m not coming off clearly for understanding
You must be leaving some vital information out of your question because I have no control over what color you make your sprites. That's going to be done in an art program (I recommend Aseprite) or programmatically with something like a color-swapping shader.
The color ramp options within the sprite customizer are limited, you can't change those. But once you export your custom sprite, you can edit the colors of the PNG as you would normally.
