Can you give me a ballpark magnitude of color difference in ΔEcmc from monitor to monitor (crt) that one might experience?
Unfortunately I cannot give you a simple answer. Two well calibrated and characterized CRT displays might agree with each other to as little as 0.5 Δcmc units for the colors that both can display. Two “off-the-shelf” CRT displays might not agree nearly so well. It is nearly impossible to guess how large the Δcmc values might get, but the displays could be different in their RGB primary colors, their white point, their tone transfer characteristics (gamma), and the characteristics of the graphics cards. These differences could result in very large Δcmc values between the displays when the same RGB values are used to drive them. I would not be at all surprised to see average Δcmc values of 20 or larger.
