A new version of Rainbow is out. This new version contains a bunch of tiny fixes that make it 10x more useful I think:
Extract color schemes from images
Extract the color scheme from any image on the page by right-clicking the image and selecting “Extract Color Scheme”:
Preview element colors
There’s now a “Preview Element Color” context menu item that will let you quickly inspect the background/text colors of any element in Rainbow’s color picker:
View last color
View whatever color was last copied/saved from the inspector with the “View Last Color” shortcut in Rainbow’s main menu:
This version also adds a French localization courtesy of Alain Besancon and some much-needed bug fixes.
I’ll be converting it to HTML, modularizing it (starting with https://github.com/harthur/color), and making it a Addon-SDK-based addon and creating a Chrome extension if all goes well.
