For people who are interested in this kind of idea, there is some research on estimating Word-Color associations.

A popular crowd-sourced dataset for this is [1] which contains average color association for 14,000 words. There is a demo available at [2].

There's also a recent work[3] trying to estimate such association using image data from Google, similar to the OP project, but a bit more sophisticated than just taking an average.
