+# vis-colorizer
+Highlights hex colors. Created for the [vis editor](https://github.com/martanne/vis).
+
+Inspired by [chrisbra/Colorizer](https://github.com/chrisbra/Colorizer).
+
+![image](https://github.com/thimc/vis-colorizer/blob/main/screenshot.png)
+
+## Usage
+
+Clone the repo to `~/.config/vis/plugins/`.
+
+Append the following line to your `visrc.lua`:
+
+	local colorizer = require('plugins/vis-colorizer')
+	colorizer.three = false -- (optional) diables three digit hex colors
+	colorizer.six   = true  -- (enabled by default) six digit hex colors
+
