I am looking for developer(s) to build website similar to "colorhexa [dot] com" in twitter bootstrap or similar design "language".
It can be developed using PHP, Python, Rails etc. The main thing I want from you is to understand how "Color wheel" works and how to calculate it using code. From there you should know about Complementary, Triadic, Tetradic, Monochromatic and other color variations and how to get them for over 16 million hex colors.
Please let me know if you are interested in working on such project and be prepared that I might ask for sample code or its interpretation on how to get "Color wheel" to make sure you are qualified for this project.
