Idea :
When copy a rgb(rx,gx,bx) values and Board would parse it and convert to rgba(rx,gx,bx,1) correctly
Most GFX charts and color picker tool work with format rgb but not with rgba which make copy/pasting in the absent of a corporate identity designer less convenient.
Workaround :
Currently you can copy paste rgb(255,0,122) but you have to edit the NaN you get otherwise nothing happened:
