Is it possible to generate Palette Colors with a Preset?

Hello,

I have an Image that need to has green Colors but I need to have a lot of Shades etc. for the Green Color. I have already a Palette with some Green Colors but I need a lot more Colors because the Palette has much more Colore in the Palette then in my Palette.

What I need is that I can for example using an Palette and then from that palette it generate a Palette for the current Sprite. Is that possible?

I don’t completely follow. Aseprite can make palettes based on the sprite. You can also save palettes as presets.

You can create some palettes using the gradient tool then shrinking it:



There is also certain tools like: Magic Pencil for Aseprite by Kacper Woźniak
that may help you in making hue shifts. (I thought there was a shortcut but couldn’t find it, although it may have been a tool).

The following may also help:

Mind rephrasing the question?
You want to make a palette from a sprite then extend/add more in-between colors to the palette?
