Google Material Hope Color theme
This theme is based on the Google Material guidelines and uses a light green color as base and an amber tone as an accent color.
Its purpose is to spread a sophisticated and calm look, thats good on the eye. To create a relaxing style that is likeable to the user, I used Nick Kolendas style guide:
The main aspects like "Relaxing", "Ruggedness" and "Systematic" lead me to the conclusion to use the Material LightGreen as a base color. The accent color "amber" then used to highlight buttons, etc. but without causing eye strain.
