I took a look at Cloud Control, and I found myself straining a bit to read grey-on-black text.
So I gave the page an audit with Chrome’s lighthouse (‘audit’ tab in Developer Tools), and sure enough it agrees with me:
1 Background and foreground colors do not have a sufficient contrast ratio.
Low-contrast text is difficult or impossible for many users to read. Learn more.
The accessibility audit reported a couple of other things, like “alt” tags for images, but the contrast issue seems like a really easy one to fix. And for the most part it looks like it’ll work well with screen-readers etc.
Hope this helps,
