A user found that two channels called "DAPI" and "DAPI 1" are both assigned the same color. This is because they both match the following regex:
'^DAPI.*$'
. Only the first match should receive the mapped color for that regex.This PR adds a check to the
getChannelColor
function that the color does not already exist in a list of used colors.
