I was trying to find an Eclipse-based color picker that worked as a view this afternoon. I can't believe nobody has created one, but from the looks of my Google searches no one has. It would really be great to have a color wheel with the features of Adobe's Kuler available right from Eclipse.
If anyone knows of a really good color swatch/picker for Eclipse, please let me know.
However, I did come across ColorCop in my search—which I'm going to try out and see how it works for me. There's no installer and it's free, with an option to donate via PayPal if you find the program useful.
Here's a list of the features ColorCop offers:
It features an eyedropper, magnifier, variable magnification levels, 3 by 3 and 5 by 5 average sampling, snap to websafe, color history, and a 42 color complementary palette. Color Cop will convert RGB decimal values to Hexadecimal color codes. It has color code support for HTML Hex, Delphi Hex, PowerBuilder, Visual Basic Hex, and Visual C++ Hex.
