Dynamic, color-sniffing cards

5 things are done to the avatar to create this card

1. Images are set as backgrounds with the size of 'cover'
2. These backgrounds are multiplied onto a slightly off-white color, to make white background avatars look slightly off-white
3. There is a slight inset shadow on the wrapper, to keep the rounded feel on images that blend too much with the white background of the card itself
4. Color detection is used on the image to extract the dominant colour, and an accent is added to the top of the card and the button
5. This colors luminance is detected to determine the right text color for the button.
