These websites use variations of light colors to create a mood for their website instead of using just white. This list show that you don’t always have to use white if you want a light colored website. Below are websites that could have been white, and probably would have looked good, but the designers pushed the boundary to create something just a little different. These websites are not white.
If you think that I missed a website or some websites that would fall into this category, let me know by putting a link in the comments. Thanks!
