Hello! I appear to have chosen a rather finicky theme colour that is confounding Ghost.
Sometimes, the website automatically makes my button text black—which is perfectly readable. On other occasions, it elects for a resplendent white visage. As you can see based on the images below, that is less than ideal. Is there any way to alter the colour of text on individual buttons / forms without moving away from my brand colour (it matches my logo)?
Those two screenshots with white text are Portal (the signup card) and the native Comments box, both run inside iframes, so custom CSS in your theme can’t reach them. Ghost decides the text colour there itself, based on your accent colour, and a mint that light is right on the edge of that calculation.
The only reliable fix is to darken the accent colour in Settings > Design a few steps until white text is readable on it. You keep the exact brand mint everywhere else: logo, theme buttons, links, all of that you can still set to the true colour with a bit of code injection.
