Judge color on equipment?

[zhxwbr8 1]

The server I am on is equipped with purple quality equipment, but the name has blue green purple.

I tried adding item id, but there are too many items.Is there any way to judge the keyword or the color of the item name?

I just want to sell items with a blue or orange name when the backpack is full, and keep items with a gold color name.

anyone can help? thanks

You can get the color from the item link, using Lua.
