RE: Pop quiz

Agree with Jim here.

I think the key here is there has to be SOMETHING (a border, background color, whatever) that is of sufficient contrast that the majority of low vision users will be able to spot the graphics. Then is there enough of the graphic that provides good contrast to allow the low vision user to interpret what they are seeing.

Hi everyone,

I’m dealing with github comments and thinking about ratios.

I think most people know the github site to some degree?

Without testing, which of these has ‘enough’ contrast for you?

[cid:image001.png@01D349BA.77467FD0]

You can probably guess the ratios, so my question is really: Is B enough for you?

The level of difficulty to meet (with various colours) goes up a lot between B & C, does the perceptibility?

To me, there is more difference between A & B than B & C, but I’m not target audience…

Kind regards,

-Alastair
