So, in my example the first 8 rectangles have blue digits beneath them and the last 4 rectangles have pink digits. It would be great if the blink color reflected the color of the digit.

This one uses the colour of the digit under the rect to determine the rect change colour.
The rects are in groups with their digits and we use classNames to find the elements in each group to get and set the correct properties.
