Questions on “Accessible Color Considerations

  1. Q: An earlier speaker mentioned black & white and possible negative impact on a segment of the community. Are there colors to avoid? Or embrace?

  2. Colleen, thank you for bringing some light to the way we should approach to colour and accessibility. I have a question: how much more costly could it be to redo a design because colors weren’t accessible?

  3. Better (that is, more accessible) to use (high contrast) color for hyperlinks or use underline / border-bottom? What about hover state effects?

  4. QUESTION: Better (that is, more accessible) to use (high contrast) color for hyperlinks or use underline / border-bottom? What about hover state effects? (thanks for this fantastic preso, Colleen!)

  5. QUESTION: do you use REM or pixels to set font sizes? If REM is used, do you calculate the REM against your browser font size pixel setting for color contrast (ratios for font differ by px size)?

  6. Question: You mentioned not using color alone to convey info. In the case of that error state on the email input field, does contrast make that sufficient, or does it need an error icon as well?

  7. So we’re not responsible if the end-user sets a default font size in their browser at < 16 px which would throw off the calculation we already set?
