Preview Color

This command allows you to preview how colours look. Also includes some information about the colour, such as its hexadecimal/decimal equivalent.

Trigger

Type: Regex
Trigger: \A(-|<@!?204255221017214977>\s*)(preview|color)(\s+|\z)

Usage

• -preview <hex> - Previews the color with the hex provided.
• -preview <dec> -dec - Previews the color with the decimal value provided.

note

The reason we have -dec is to distinguish hex from decimal in ambiguous cases. For example, 111111 is both a valid hex and decimal color.

Aliases

Instead of preview, you can also use color.
