I created this chart originally in LAB colour mode as that is the most accurate colour table for print and then added the closet RGB values as well. Obviously, print colour is a lot less saturated than screen colours but by tweaking your screen and calculating your colour values in LAB you can achieve quite accurate colour renditions of even the most vibrant colours including Pantone specials. Before uploading this, it was profile converted to sRGB, which should give the best representation on screen. If you’d like to test the match between your screen and printer accuracy, you could print this out in RGB and also try printing it in LAB colour space if your printer supports that and compare the differences between the two.
if the fact that the RGB conversion has caused any problems - let me know and I will make a hi res version available in its original LAB colour space on a server somewhere for any of you to download.
