RE: Non-text contrast comment

Agree with Jon's assessments.

From my perspective of someone using invert colors, the text-to-background
contrast ratio of row #2 is the worst.

Row 1 would actually be my overall preference, except for that 5th button
from the left, which could for blend in with my dark background if viewed
as a stand-alone button. The button in the same position (5th from left) in
Row 4 would be better.

Hi Alastair, the darker text on the background for row # 2 is worse for me
in regards to reading the text.  Finding the button boundaries are not an
issue for me with any of your examples.  #4 is my preference but is not
necessary.   The text contrast is far more important for me.

Hi everyone,

The attached doc is a (public) comment on non-text contrast and buttons.

It’s a useful format as they’ve shown some examples.

We’ll have to deal with it pretty rapidly, I’m interested though if you
could look at the last section with the 4 rows of buttons and say:

      Is the 1st row noticeably poor contrast for the buttons? I.e. would
      it be hard to find/discern them?
      Are rows 2-4 better? If so, which is best?

The first bullet of non-text contrast is proving to be the most difficult,
whereas I had thought it would be the second bullet!

Cheers,

-Alastair
