first of all you must have installed greenlight installed on server
for changing the color of theme :
vim config/application.rb
scroll down and you will found following code just replace code of color with your desire:
# Default primary color if the user does not specify one
config.primary_color_default = "#116ceb"
# Default primary color lighten if the user does not specify one
config.primary_color_lighten_default = "#e8eff9"
# Default primary color darken if the user does not specify one.
config.primary_color_darken_default = "#316cbe"
there is lots of things you can customize..(almost everything).
And one of the most important thing after making changes to any file you must have to rebuild your image of docker you can do that by running the command which is given at the end.
This command is for default settings if you have changed the name of your image please replace bigbluebutton/greenlight release-v2
with yourimage name.
you will find your image name here:
#this will open the yml file for docker settings
vim docker-compose.yml
#file will look like this:
ersion: '3'
services:
app:
entrypoint: [bin/start]
image: bigbluebutton/greenlight:release-v2 #nmae of your image
container_name: greenlight-v2
env_file: .env
restart: unless-stopped
ports:
- 127.0.0.1:5000:80
copy this command and past into the terminal blow command for rebuilding your docker image
docker-compose down && ./scripts/image_build.sh bigbluebutton/greenlight release-v2 && docker-compose up -d
