Great work - as usual !

One suggestion from my side as amateur: it would be great if there would be a function "setColor" so that the slider can be set to a specific color by the program . For example a user selects a color for drawing and wants to change it a bit later, so the slider would start at the color of the selected object.
Does that make any sense ?

Greetings,
Chris

then the user can set the slider to this color? or is it about being able to set a specific color at the beginning? But if this color does not exist in your palette, then he will not be able to return to this color.
 
Good Job!
Two suggestions:

1) that you can choose between horizontal and vertical position
2) Adding Alpha, for example, it is currently not possible to choose grayscale or pale color tones.

you can add whatever you want to the palette, it just has to be an image. But I think that is not possible to pack an alpha value in a picture. Paint apps surely have their own slider with a value for that.
