Allow copy/paste of hex codes

Hello, Linga team.

I often work with clients who wish for their POS buttons to be specific colors, for easier recognition especially if they have a lot of items for sale.

I believe allowing us to copy and paste hex codes into the color selection screen would be of great help and not too difficult to achieve. Currently, we can see the hex codes but can't select or change them manually (as pictured below).

Thank you for your time and hope you can consider this idea.
