Thanks! I was trying to decipher it on iMac with a 5k display (? 5120x2880) and an attached LED Cinema Display (2560x1440). MacOS does a good job dealing with the DPI so that they appear the same size (but one is clearer than the other). Using a magnifying glass, I could almost make out the text on the lower DPI screen, though blue was almost invisible, and I could not seen anything other than a colored bar on the high DPI screen :)
