In Room Manager, you can set different colors for each room in the system. You can use default system palette or use hex color picker tool.

Font Color - the color of text (room name and prices)

Header Color - the color of the header (the line with room name and dates)

Background Color - the color of bed lines in the room list

You can select color from the default palette:

Or you can use hex colors. Just search HEX COLOR on Google and select the color from the palette. A HEX color has a # and 6 signs, for example: #d3e4ed, #fcfcfc, #f6d9d9.

Copy the code of the selected color from Google and then paste it in Room Manager.
