Regex - how to negate one word and one word only?

Question

How do I write a regex expression that matches these lines

<color>blue</color>
<color>green</color>
<color>blackish</color>
<color>offblack</color>

But not this

should it only match `n` (except where n = black) or ANY line except black (I.e. would `I like turtles`) be match or a non-match — JeffUK, Jun 27 '17 at 15:03
