Apple iMessage Green bubbles fail accessibility WCAG colour contrast

So apparently in the US, users care about blue bubbles and green bubbles within iMessage.

While that “conversation” happens, what was highlighted was these green bubbles don’t even pass colour contrast checks, meaning they’re not as accessible as they could be.

For those uninitiated, accessibility is about building digital products that are inclusive of disabled users. These internation technical standards are called WCAG. Part of this technical specification includes Contrast (Minimum) (Level AA) under 1.4.3

I’m not sure why this has been missed, or what prevents darkening the green to pass simple colour contrast checks…
