I am a 'mild protan', meaning I have a mild form of red-green deficiency known as protanopia. Color deficiencies aren't normally considered a disability, but it does cause their fair share of issues. Issues can be mild to full on embarrassing; Eg. buying clothes, seeing stop signs, flashing yellow vs flashing red lights, etc.
From a gardening standpoint, it can be hard to tell when fruit is ripe or unripe, when leaves are turning or drying out and turning brown, identifying plants, or in some cases being able to tell if a plant is alive or dead.

I'm curious if there are any fellow gardeners here that have a color deficiency or someone close to them that is and if anyone has ever had any challenges of such, how it was overcome, etc. I wonder if anyone has ever designed a garden around a color deficiency so that things would pop out more to them, or even just be more identifiable.

Though I don't have a problem w/ colors, I do have an eye problem resultant of a detached retina that didn't re-attach properly, 7 surgeries later, still no resolution. Due to the problem I neglected my rather extensive garden and it sank into a large weed patch that I'll have to repair this summer. The eye itself really wasn't the problem, my psychological attitude about the eye was the root cause. I've finally pulled myself out of that hole resolving to rectify my error, and feel better about the situation.

I just wanted you to know there are other gardeners out there with eye problems and gardening is a good solution to offset problems we encounter. Designing a garden around your problem sounds like an ambitious project that completed will do a doer proud. Gardeners are innovative and solution orientated.

James, my non-gardening husband who is color blind prefers conifers and evergreens over flowers. In fact, he rarely notices flowers in the garden unless I point them out to him.

He does have difficulty identifying ripe vs green bananas.

Have you heard of new glasses that "fix" color blindness? There are a couple of different technologies out there but EnChroma seems to be the most popular brand. You can google youtube videos of people trying it out for the first time.

Bananas are the worst. Every time I think that I have picked out the best bananas, I get home, and then get that "look" because they're always green. Lol. I always have to ask random strangers in stores what color things are. Most people are very kind about it and helpful and we just laugh together about the experience--hopefully it gives them a good story.

Yeah, I do rather enjoy evergreens. Just yesterday actually my sister and brother-in-law were discussing "what kind of bush flowers that way? The flowers are so red!" Cut to me, scanning and searching everywhere, and then after asking where and getting the exact location of the bush, I could only shrug, because there were no red flowers that I could see.

YES! I have wanted some enchroma glasses ever since they first came out. Their prices are slowly dropping as the technology advances. Just waiting for my moment
