Allow choosing color range

[Turhvjbufv]

Sorry for the long read.

My wallpaper have a lot of different colors in them, and color blender chooses the dominant color, please add an option so that color blender will choose a material color based on a range. Example: let's say I set the range from purple to green(which also means that blue ext is included), and my current wallpaper has the colors yellow, red and blue, blue is the least dominant tho so usually it would choose yellow, but because I set the range from purple to green and red and yellow aren't in there, it chooses blue as the material color
