i have made an app that takes random colors from Hexbot and a random picture from Unsplash, when you click the picture it applies a Pointillism effect with the random colors.
This is the app: https://hexbot-pointillism.herokuapp.com
If it doesn’t works is because Unsplash allows me to request only 50 images per hour in the demo version.
I hope you like it!
Note: I use PHP just to take the enviroment variable needed for Unsplash from Heroku.
