Sometimes I make signs using Illustrator and Photoshop at work.
This is the first time I've heard of Universal Design.

I looked up the color-weakness . I found the word Universal Design.

Thanks! I still find the idea of という is still not natural to me, like i can't quite convert it to my other languages to make good sense of it. For example, i would most instinctively just convert it to 色盲を知っている without all the extra things! So I am still getting used to that.

It is interesting that you brought up Universal Design, I looked it up and it is basically the idea of color-blind/color-friendly mode that we often choose for games. For example, many board games nowadays would draw symbols along with colors so that players can tell which card is which even if they have problems with color. And in information technology, we often have to consider this for web accessibility for user friendliest, e.g. self descriptive symbol instead of words/colors.

When I write a document, I often use the “〜という”.

I looked it up. the meaning of “〜という” it said that it is used when explaining the names of people or places that the other person doesn't know.

such as
○私の住んでる街には「西条寺」というお寺があります。
○私は島根県の松江という所から来ました。
○進撃の巨人というアニメを知っていますか？

「という」にはまだ意味があるので、ここに書きますね。少し時間を下さい。

Another use and its explanation.
1. It explains a certain word and topic.
such as
「箸」という単語の読み方は「はし」と読みます。
2. For as a reason the previous phrase, and it shows next a result or a development.
such as
「雷雨」という言葉を検索すると、「らいう」と出てきました。

3. Tell what someone said and what was written.
　such as
社長が「早くしなさい」という事を言ってたけど、なんの事だろうか？
4. Emphasize or give examples of specific matters.
　such as
黒猫に「ナイト」という名前を付けました。

Thanks for your detailed explanation! I think I have a better idea of how it can be used now. On the other hand, I still have uncertainty on when it can be omitted. Take for example "社長が「早くしなさい」という事を言ってた", I would most likely have written as "社長が「早くしなさい」と言ってた" as i thought that is already enough.

「社長が「早くしなさい」と言ってた」
It’s ok to write like that.

Okay! Thank you. 😊

ありがとうございました！

すみません、下手な冗談でした！ ^^;; 私の住んでいた国では、「赤黄緑」信号の位置は「上中下」なので、位置さえ分ければ、色を見分ける必要がありませんね。

なるほど　😊
