Accessibility - Colour Blindness

Hi Heroes,

I'm working on a Storyline project that includes accessibility considerations. I'm very interested in your design experiences of visual impairment and colour-blindness. I'd like to include a slider interaction where the learner needs to slide a beer glass (slider button) to the matching colour on a colour pallete. Some online articles and guidelines suggested to use a "pattern" instead of colour.

Please review the example and share your thoughts. Have you worked on any projects tailored for color-blind users? What design strategies did you employ to accommodate them? Thank  you!
