Suggestion: Color Names to Hex Codes for blocks (Hot Tan = 0x?)

Also you can find that on fourth page of this sheet:

Finding Rock Colours!

I share a summary sheet instead of forum-driven materials catalogue. It includes all data captured by @Angellus and myself. Please, feel free to comment it if you have additional information. UPD: With indispensable help by @nevir the colour sheet was updated with… colours! It has visualisation now so you can find you need in by its colour. Look at second page with vertical sweep [%D0%B8%D0%B7%D0%BE%D0%B1%D1%80%D0%B0%D0%B6%D0%B5%D0%BD%D0%B8%D0%B5]

Thanks @Nevir for that.
