RGB Chart & Multi-tool ...

FS 11630 Pink

For graphics rather than models etc, but I find the Color Search and Color Conversions tool
to be fun. Especially for writing serious sounding articles in which one can proclaim things like
BS381 454 Pale Roundel Red is a 92% match for FS 11630 Pink.  

Have fun.
