This is a personal project trying to solve this question: What is the exact color (RGB) when given a spectrum? As we know, a spectrum is the only way to describ a color without any ambiguity. Given a spectrum we can see and repreduce a color exactly the same, theoretically.
I have write a series blogs explaining the outline and details of the whole thing. You can checkout these blogs at OpticPhantasm, my special column at Zhihu.
Codes have been merged into my color science tools. This repository will not update.
Please go and check the new repository. Thanks!
