Change bullet color in Rise

Just a note to say that I've been looking for ways to fix this with issue using purely CSS, and haven't found one that works well enough. I was exploring using the color 'mix-blend-mode' as a means of ensuring high contrast colors on the bullets, but this of course would do nothing to match the bullets to the text (https://codepen.io/rebelchris/pen/dyoaWRa).

Until the Articulate team fixes this (if ever), my personal recommendation would be to make use of the bulleted list block when you are going to use a darker background. This won't match the color of the text, but it will at least use your accent color for the bullets which in theory would be a higher contrast than the dark grey bullets on a darker background. The challenge with this recommendation is that the style of the bulleted list block is very different from the bulleted list style that is applied within a normal text block in Rise. 

If there is interest in having these two different styles mimic each other in terms of spacing between bullet and text, just let me know and I can customize that bit of CSS, and share the code here to at least give you one alternative avenue if this issue is actively causing headaches with your content.
