I measured the contrast on your example and it is 1.27:1.  That certainly fails, and probably isn’t the right example for a question about whether 3:1 is sufficient…

Hi,

I have a question. I know large text that pass color contrast ratio of 3:1 would pass the color contrast. Is it possible to consider this as failure if it is barely readable with black and white or color blinded people?
