In today’s online world it is not optional to ensure that all you do is accessible to all. One big part of accessibility is color choice. I am not color blind but I can’t tell you how often I have been on sites where I can’t read the text due to poor choices of color.
Pika solves for that and is extremely easy to use. Pika allows you to see how your color choices contrast and how appropriate (or not) they are to use to be compliant.
When I am working on anything online, I always have Pika open. Can’t overstate the importance of this or how useful Pika is.
