Halp! For the life of me I cant add a red triangle (pointing up) to a sign. I’ve done it before so I know it works, but can’t do it today. Most lists show it as:

No problem 
I copied them all into a spreadsheet (Apple Numbers, sorry everyone) as backup and so I can add notes to emojis like color, size, if they look particularly good on certain signs, etc. I’d be willing to copy that to a more widely used online sheet, or even just post screenshots of the lists to some kind of blog.

I use this website.
When you select the emoji you click the technical info button and it tells you the code.
You don’t use the U+ part of the codes.

I would suggest not using screenshots so lazy people like me, lol, can copy and poaste ;)))
I usually use this google doc someone made. It lists all the keywords you can use as well as the actual name of the emojis. Boundless - Emoji - Google Sheets
I tried several sites though now I think it was user error since i was using the U+. I never said I was smart, just that I like purple.
