I won't have time to debunk the old "yellow is not accessible" myth in my axe-con talk.
But, you are lucky: I already wrote a whole article on how accessibility does NOT limit color choices.
What limits your choices is a lack of knowledge, and / or creativity. I can't do anything about creativity, but, I can help you with accessibility knowledge.
I built six WCAG-tested palettes to show that accessibility doesn’t limit creativity.
