Remove color:#000000 but not stop-color:#000000 with sed?

Question

linux

Greetings!
There is this line:

style="color:#000000;stop-color:#000000;solid-color:#000000;"

It must be removed from it color:#000000so as not to change the other two.
Only got to

sed -r 's/[^-]color:#([0-9a-zA-Z]{3}|[0-9a-zA-Z]{6});?//g'

but such an expression removes the preceding character ".

I'll suggest as an option:

sed -r 's/([^-])color:#([0-9a-zA-Z]{3}|[0-9a-zA-Z]{6});?/\1/g'
