Instructions
Choose which color you'd like to use. "RuneScape" chat supports five different colors: cyan, green, purple, red and white.
Type your chosen color within the chat field, followed by a colon. Use all lowercase letters. For example, if you want to color your text red, type "red:".
Add your message directly after the color code. Do not put a space between the colon and the text. If you want your red text to read "Hello!", type "red:Hello!". This color will not carry over to your next line of text.
