+# viscolourchanger
+
+## Intro
+viscolourchanger is a program to dynamically change the colourscheme used by [cli-visualizer](https://github.com/dpayne/cli-visualizer) (herein referred to as 'vis'), as generated by [pywal](https://github.com/dylanaraps/pywal).

+
+
+
+##Setup and Configuration
+###Initial Setup
+To make vis recognise the generated colour scheme, it is necessary to add the line
+
+> colors.scheme=wal
+
+to the vis config file located at $HOME/.config/vis.config. 
+
+(It is also helpful to add the line 
+
+>audio.stereo.enabled=false 
+
+in order to see a broader range of colours in the base vis config, but this is just personal taste and far more complex configurations are possible.)
+
+###Further Suggestions
+That is all there is to viscolourchanger itself, and in absence of something further, pywal and viscolourchanger run separately. However, it is useful to make a wrapper for pywal. A simple wrapper which I have written is located [here](https://git.lynnesbian.space/petra-fied/viscolourchanger/src/branch/master/wal), and will allow for on-the-fly colour changes as pywal is run.
