There’s no doubt that colorblindguys need a little help. Many of us purchase an item thinking it’s one color and it’s a totally different color. I’ve purchased purple items thinking they were gray.
Another dilemma is when I’m confronted with a loaf or bread that I know is not brand new. Since I don’t pick up on the green color once it’s started to go moldy, I take a picture of the bread and send it to my daughter. This shot of bread was from 2016 and declared able to be eaten. I hope to do a test taking a picture every day of some bread and seeing when it starts to get moldy.
There’s a web site colourblindawareness.com that provides helpful information about colourblindness. Notice the spelling of coloublind/colorblind they are based out of Aylesbury, England.
