Awesome websites to find colour palettes
ColourLovers
I remember using this tool many years ago because it had so many colour palettes. The way the palettes were built showed a higher percentage of certain colors, which helped me imagine how my website, design, or app would look when I used certain colours more than others.
Flat UI Colors 2
If you are looking for a large colour palette of more than 4 colours, this website is the right one for you.
Color Hunt
I discovered this one on http://producthunt.com and it has a very good collection of colour palettes presented in a clean website.
Trianglify.io
This website allows you to test your colour palette in a gradient tool.
