### 3/5 — 色の判別が不正確

*2024-01-29, version 2.0.0*

色を作ることが多いので、便利そうだと思い買いました。 アイホンのカメラが判別した色で判定されてしまう。白を写すと薄い灰色、黒を写すと濃い青または濃い紫と表示。いや、白は白だし黒は黒でしょ笑 茶色を写すと灰味の青、明らかに茶色の財布なんだけど、確かにアイホンのカメラを通すとチャコールっぽくも見え、それで灰味の青と表示されてしまう。。 使い方慣れてないだけかも知れないが、有料の割には使えない。無料の色判定カメラの方が使いやすい。

### 5/5 — 類似アプリ中最も使い易い

*2024-01-12, version 2.0.0*

Windows版「色々の色」と同様なものがリアルで使えたらと思ってましたが、まさにそのニーズにピッタリ。 色の名前が知りたいという色弱の悩みが解消できます。 余計な操作が必要なく直感的に使えて、最高です！

### 5/5 — とても分かりやすくてかなり良い

*2022-09-18, version 2.0.0*

このアプリは明暗、何色に近いのかがバーで見てすぐに分かる工夫がされています。とても重宝しています。色の判定も難しい色で表示されず、聞き覚えのある色に濃い、薄いの表現で教えてくれるので分かりやすいです。色覚特性のある私はこのアプリにかなり頼っています。残念なのは、iOSにしか対応していない事です。Androidに機種変更して、かなり困っています。どうか、Android版でも出して頂きたいです。よろしくお願いします。

### 5/5 — 色弱には必須ツール

*2022-02-26, version 2.0.0*

すばらしいアプリです！
要望が2つあります。
・20秒ほどで画面が暗くなるので、暗くならないようにしてほしい
・LEDのON/OFFボタンをつけてほしい（認識精度向上）
ご検討宜しくお願いします！
iPhone 13、iOS 15.3

### 5/5 — 色弱の必須ツール！！

*2022-02-26, version 2.0.0*

類似の別アプリを利用しましたが、精度がいまいちだったのでこちらを購入。わかりやすいし、とても便利です。色弱の人は絶対購入すべきアプリです。
さて、開発者様にいくつか要望があります。
1. 20秒すると画面が暗くなってしまいます。iOSの「画面注視認識機能」をオンにしていてもです。これは少し不便なので、使用中は画面を暗くしない、あるいは画面注視認識機能に対応してほしいです。
2. 部屋のライティングによって真っ白なものでも灰色と認識されますが、iPhoneのLEDをオンにするボタンがあると、薄暗い部屋でも認識精度がより高くなるのではないか思いました。
最後に、このようなすばらしいアプリを開発していただき、本当にありがとうございます！！
利用環境：iPhone 13, iOS 15.3

### 5/5 — Very Useful!

*2021-09-10*

This is app is very useful to learn colors that are in the world. I’m grateful this app exists and it would be complete if it allowed me to check out colors on the photos I already have in my Library. Otherwise, I use this app a lot. Thank you for creating it!

### 1/5 — It will not work

*2020-05-22*

It does not work

### 5/5 — Very neat

*2020-02-01*

Really neat app and works very well!

It’d be great if I could import photos taken outside the app and use the crosshair on them too.

### 5/5 — カラーホイールに色名が！

*2019-08-20, version 1.0.0*

カラーホイールに色名が付いている稀有なアプリです。色弱の私には色名が付いていることで多くのことが学べます。色弱の子供たちに教えてあげたいツールです。

### 4/5 — 良かったです

*2019-08-09, version 1.0.0*

色がわかりやすくなってすごく良かったです！
