为什么我不能使用某些在嵌入的字母中包含字母的十六进制颜色？

Question

I'm trying to use HEX-color with letters (ex. 2c2f33) and it doesn't work, but If I use something as "3447003" it works. So what should I do to make it work?

message.channel.send({embed: {
      color: 2c2f33,
      fields: [
        { name: "Gaming Roles:", value: "<:gta:605106790534742057><@&587234726834733056>\n<:r6s:605106790677348372><@&587234959752822824>\n<:Fortnite:605106790580879361><@&587461980172976168>\n󠇰<:pubg:605106790690193428><@&587240268068159497>\n<:arma:605109711703900170><@&587238820890804224>\n<:division:605106790673416202><@&587239012909973517>", inline: true}
      ]

Answer 1

A color field within an embed object in Discord's Javascript API is of the type integer , meaning that it will only take a number as a value. The Hexadecimal number system is of base 16, meaning that the first 16 numbers are represented using 16 different symbols (0-9, AF). Because the color field can only take numeric characters and not alphanumeric characters, Hexadecimal doesn't work. Thus, Discord's API team decided to use the vastly more common decimal (base 10) number system, the system we use every day with 10 symbols that are all numeric characters. This way, the input in your code will only be numbers.

You have two options that I can think of:

1. Convert your colors yourself from Hexadecimal to Decimal, then use the result in your program instead of the hex code. The math needed to do this by hand is off-topic, but I can link you to this website to do it for you. This option can be somewhat tedious (even if you use a website) because of the copying and pasting.

2. put 0x before your hex code in the code. I'm not 100% sure this would work in JS; What it does is it marks the number as being hexadecimal, then converts it to decimal for you.

Answer 2

Use a string containing your hexadecimal value.

embed: {
  color: "2c2f33",
  fields: [...]
}

When creating a RichEmbed , the color property can be set to a ColorResolvable , so it can be any of the following:

• Hex Literal
• Hex String
• Number
• RGB Array
• See hyperlinked documentation page for a list of pre-defined strings.
