This is the colour scheme I am going to use for my app. I wanted to use colours which were fresh and organic as ‘FEED’ is a food app. I believe these colours work well and would work well with the gradient too (the darker colours are 50% darker than the colours on right). Ive also added a drop shadow as it really makes the colours pop and they help identify where the buttons are.
I believe the colours will work well with the 60, 30, 10 rule.
