well actually, that custom colour reel in google sheets notes the colour code of the colour you're on and lets you type the one you want if you already know it. I approximated the default colour of the forums for the background and typed in the colour codes I listed as the text colour so you can tell what it'll look like at a glance, on top of being able to just copy paste the full BB code, [][/] part and all as needed. Right now, it only really has a number of reds, pinks and purples since technical difficulties trying to edit it from my phone cost me most of the codes I had before I realized I could use sheets to list them more effectively as well as potentially share them. Like I said, you can look up a bunch of colours with their codes listed, so I guess what matters is that I have a decent list of the main colours. I think paint sample colour sheets have the codes on them too. I'll probably have to make a separate sheet with white background for the ones with poor contrast on dark backgrounds, as the forums have multiple colour skins.
