Option to automatically colour text that is a colour by its colour in the text of synthesis.

and "colourless"?

It's a cute idea, even having a colour picker in the UI (though subjective) could be nice to match your samples to. @kjappelbaum did something very nice on this in https://doi.org/10.1039/D0SC05337F if we want more inspiration
