Popup color from color string like `#f2d3aa` with Emacs

Question

I'm using scss-mode in Emacs.

There are a lot of color string like #f2d3aa in text.

I wonder if there is a function that pop up a color square from string of current position.

Is there a emacs function like this?

Answer 1

I'm using rainbow-mode. It's a minor mode that fontifies the text color descriptions as you type them.

Very user-friendly, since it's got only one interactive function (i.e. rainbow-mode). It's available from MELPA.

Answer 2

Here are a couple of tools that can help:

• hexcolour.el -- shows such hex color codes in their own color in the text

• palette.el -- interactive color palette: takes such hex codes as input and provides them as output (in addition to color names etc.)

• hexrgb.el -- (used by the color palette and other libraries) color manipulation functions

The first one, hexcolour.el, is the closest to what you asked for.
