Colorblind mode for critical successes and failures

There's a colorblind player in one of my groups, who didn't know until 20 minutes ago that critical failures and critical successes showed up as different colors. Red and green, after all. It doesn't seem to impact functionality for them, but it seems like a bummer. Is there an option somewhere to change how the colors show up, as a courtesy?

Not in Roll20 itself, but you could probably create a stylish css mod to do it. Out of curiosity, which character sheet are you using? It could also be done via the char sheet's roll templates (I believe)

Would something like this work?  Left to right: Critical Success, Both, Critical Fail You can get the Stylish plugin for their browser, and use this stylish theme: /* Critical Success */ .inlinerollresult.fullcrit, .diceroll.critsuccess {     border: 8px dotted #3FB315 !important; } /* Both */ .inlinerollresult.importantroll, .diceroll.critsuccess.critfail {     border: 8px groove gray !important; } /* Critical Fail */ .inlinerollresult.fullfail, .diceroll.critfail {     border: 8px double #b31515 !important; }
