At the moment, you can trigger the colour search widget using a hex colour in the format #ff0066.
I propose that it also trigger on hex colours without the trailing "#".
Though this may cause some conflicts with other queries, i can't see it being a concern.
Entering a hex-colour code without the trailing "#". Useful when copying from input fields quickly that don't append the # by default. Could save a little time and annoyance.
Example:
User uses ShareX's screen colour picker to quickly grab a hex code.
User then needs to paste this in, then add the "#" prefix.
This change would eliminate the requirement of adding the prefix.
