## What is ColorDeBlind?

See the world the way a color blind person sees it, or recolor it so the differences you've been missing become obvious.

FOUR WAYS TO SEE COLOR
• Simulate — view any scene as someone with protanopia, deuteranopia, tritanopia, or achromatopsia sees it.
• Correct — remap colors that would blur together onto ones you can still tell apart.
• Highlight — flag only the regions likely to be confused, in four styles: Tint, Spotlight, Heatmap, and Opponent.
• Color ID — aim the crosshair at anything and get the color's name, its Hex, RGB, or CMYK value, and how close the match is.

IF YOU'RE COLOR BLIND
Sort the laundry. Tell ripe fruit from unripe. Read a transit map, a stock chart, a wiring diagram. Color ID names what you're pointing at. Correct and Highlight run on the live view, so you can simply look — nothing to capture, nothing to wait for.

IF YOU'RE NOT
Red-green color blindness affects roughly one man in twelve. Hold your phone up to a chart, a slide, an app, a sign, or an outfit and see at once whether it still reads. Swipe the carousel to compare every type side by side against normal vision.

COLOR VISION TEST
A built-in test using Ishihara plates. Tap through, choose what you see, and get an estimate of whether you may have a red-green deficiency and which type it leans toward. Afterward, review every plate: what you answered, what normal vision reads, and what that plate was testing. This is a screening aid.

KEEP WHAT YOU SEE
The shutter saves the filtered frame straight to Photos, or import a picture from your library and filter that instead. Switch on Fade and the preview cross-fades between the unfiltered scene and the filter on a loop; captures then save as Live Photos that animate the same way, so you can press and hold in Photos to show someone the difference.

Everything runs on your device. The camera feed never leaves your phone.

"This app will change the lives of color blind people in ways that no medical advancement has ever been able to. It's convenient, practical, and more importantly, useful to people who had previously been unable to distinguish between various colors. Aside from it's medical implications, it's also really helpful in showing people who are not color blind how debilitating and frustrating the condition can be." -Samantha Harris, M.D.

"Holy crap. That is amazing. I can see things I could never see before." - Tony D. (red-green color blind)

### 1/5 — 画质会降低点开“色彩标识”会闪退

### 4/5 — A bit clunky.

*2023-12-11*

I like it, though it could have simulation of partial color deficiency, maybe with a slider for how much. It might also use some “About…” text popup that explains the app and how to use it.

The single-view display does not clearly show what processing is applied to that view, or how to change it. No processing is only displayed when doing color-value capture with a square at the center of the view.

The multiview could also include no processing. It could display only deficiency selection, only color enhancement, or making some color white, making 4 at a time.

One might also mention simulating dog vision - dogs have red-green color deficiency.

### 5/5 — 极好的软件

非常好，终于能够看清图谱上自己看不到的图像，知道那些数字图案在什么地方了，心里更有底了。

### 5/5 — A tool every colorblind person should own

*2019-11-25*

I am red-green colorblind and for most of my life was stuck with the game “what color is that” and “what color does that look like.” These are games that non-colorblind people play in trying to understand color blindness. What they don’t understand is that colorblind people can’t do that. They can’t see the colors the same way and don’t have a common reference point for describing the colors. 

When I purchased this app 4-5 years ago I was caught in a problem of picking colors to paint my house. My friend would show me paint samples that looked, to me, exactly alike and ask me which I preferred. (To her they looked quite different.) When I would say they look exactly alike, she would get upset thinking I just wasn’t interested. Then I downloaded the app and tried it out by taking a picture of the paint samples and, from the “how colorblind people see it” asked her to pick which one she liked best. Her answer “they all look the same” followed by “oh wait, when you tell me they all look the same you mean that they all look the same.” The tension of the moment went away instantly. 

Since then, this story has repeated itself more times than I can imagine. Somebody would say “look at the colors of this” and I don’t get it. So I whip out my app and say “this is what I see” and they get it right away. “Oh, you can see that the leaves have changed colors, but you can’t see all the color variation. I get it.” 

Besides helping me relate to others, this app has a few useful features that I use whenever I’m in a quandary about color. The “helps colorblind people distinguish colors” feature lets me quickly see “oh, I bet I’m not understanding something others see here.” It also lets me quickly figure out which shirt is purple and which is simply blue. The color ID feature then lets me zero in on particular things and get a rough idea of the color other people will say something is.

So I super highly recommend this app to anybody who’s colorblind and frustrated with color-sensitive people just not getting it.

### 5/5 — Amazing

*2019-02-18*

I have protanopia colorblindness, this app really helps me. It also helps my family see what I see 🙂. Would really recommend this.

### 5/5 — Very cool!

*2018-08-22*

Who knew colorblind people see so crappy??! Jk. But seriously. I like the app.

### 5/5 — Incredible parenting tool!

*2018-01-29*

I have a 6-year-old with protanopia and after a frustrating experience with a board game that we had to take a Sharpie to to make it useable to him, I stumbled across a forum that sent me to your app.

This. Is. Amazing! After years of trying to guess which colors were challenging to him in each context, I can literally see for myself! I spent about 20 minutes just walking around my house with my mouth agape, seeing our home -and us! -the way he does. It is rare that we can truly experience what a challenge is like for someone else -and this app did just that. (I see what he means: unripe and ripe bananas are identical!)

This is going to be an incredibly helpful tool for us and I'm going to tell his teachers about this app too. Thank you for quite literally giving us a view into his world.

### 5/5 — Wow...

*2018-01-15*

Until I saw this app I never knew I was colorblind. I thought everyone saw what I did..... apparently not.

### 5/5 — What would I do without it?

*2017-05-27*

I love being able to use this app to see what my graphs will look like to my team members who can't always distinguish between colors.

### 5/5 — Helpful to a mom of a colorblind 5-year old.

*2015-03-11*

When I recently learned my son was colorblind I felt really sad for him. Through using this app to see the world as he sees it I have begun to appreciate the more subtle beauty of the world in shades of blue and yellow. It's also really useful when considering books to get for him and other teaching materials. I can see when things get lost in the background. Only thing I would change is when you take the picture for comparison you would have the option to save it to your photo album.
