Yes, we also need the ability to change text color by person along with changing their bubble color. Currently, if I've chosen white or light gray as the default text color, it prevents me from ever giving anyone a light bubble color, because there's not enough contrast to easily read their texts. Likewise, if I've chosen the darker text colors, I can never give anyone a darker bubble color. It's really quite limiting!

More colors! More lighter colors! More darker colors! More grayer colors! Better yet, just add an option to select colors by hex or RGB numbers or from that full rainbow color palette box with it'd lightnesd/darkness slider.
