Question

In JavaScript I have used the JQuery plugin xcolor, which is a fantastic little tool for working with colors. It has color string parsers, all the color space conversion methods, a few color filters, and my favorite, a gradient generator (see $.xcolor.gradientlevel()).

I’m looking for something similar in Java. Other bonuses would be falsecolor routines (convert a number to a color – a powerful one would have parameters like max/min cutoff and log vs. linear scales) and color schemes (like red -> orange -> yellow -> green gradient generator).

Are there any free libraries out there that can do some of these things in Java or is this something I have to roll myself? I haven’t found much from my googling except for some things in AWT, but I need it to be generic because I’m not working with any Java GUI stuff at all.

Answer 1

Java’s Color class should work fine:

Color.brighter()
Color.darker()

Gradients:

Generating gradients programmatically?

Hue Saturation: Color.getHSBColor(hue, saturation, brightness)
