### Highlight Current Context
By default, current context is highlighted by yellow foreground & black background
It is configurable by setting environment variables `KUBECTX_CURRENT_FGCOLOR` & `KUBECTX_CURRENT_BGCOLOR`
To change foreground colour to Blue for highlighting current context:
`export KUBECTX_CURRENT_FGCOLOR=$(tput setaf 6)`
To change background colour to White for highlighting current context:
`export KUBECTX_CURRENT_FGCOLOR=$(tput setaf 7)`
Refer color codes [here](https://linux.101hacks.com/ps1-examples/prompt-color-using-tput/)
