None of the options other than grayscale work for me.

Loved using this to ensure my products were colorblind accessible. Includes a lot more colorblind options than other tests I've used. Other tests don't include vision loss either. Worked great for a long time but more recently has been lagging or just not working at all. Think it's been a number of years since it's been updated. A new update is needed please!
