RGB to Indexed Mode changes colors

[dacap]

Welcome @jodie! The conversion from RGB to Indexed uses the current palette, you can try to create a specific palette for your sprite before and then try to convert the color mode:

How to create a palette with the colors of the current sprite?

You can create a new palette from the active colors of the sprite selecting the [☰] button and then Create Palette from Current Sprite: [createpal] You will see the Palette from Sprite dialog: [dialog]

Anyway if you have too many colors (more than 256) in your image, there can be some difference in the final result. We’re working on some fixes about this for the next version (not sure if v1.2.18 or v1.2.19).
