Shouldn't gray and grey be treated as the same word?

They should be de-duplicated imho ..

snippets from /www.quora.com

In digital circuits there is a form of encoding technique which is known as “gray” encoding used in Boolean expression while there is nothing called as “grey” encoding.

The colour code used for “grey” is (#D3D3D3) represented in hexadecimal and it's decimal representation in RGB format is (211,211,211) while the colour code used for “ gray” is (#808080) represented in hexadecimal and it's decimal representation in RGB format is (128,128,128).

Yeah. Except in HTML where they are color, not colour codes ;)

hahaha

nah, it is usual kind of fun in empathy :)

TIL there're two spellings for moustache/mustache too

(Though I put 'beard' in my answer :-P)
