Feature request: Allow defining colors manually

[ronilaukkarinen]

Is your feature request related to a problem? Please describe.
Feature request: Allow defining hex manually when clicking the color. Now it's only possible to pick the color. Sometimes I already know the colors and it takes time to go and pick them from the screen. We should be able to input colors natively.

Describe the solution you'd like
When clicking the Foreground and Background, allow inputting the color. Or alternatively from the right click context menu when right clicking the color area. Or both.

Thanks for flagging this issue. It looks like a duplicate of #57, so going to close in favour of that.
