Does anyone know of an RGB colour adjustments settings website

I remember seeing online a website that would help you correct your colour settings.

i.e. Your printer was printing out Greys with a bluish tint, it would say which way to slide the Cyan, Magenta or the Yellow.

Can't for the life of me remeber it and it's nowhere in my favourites folder.

Can anyone input?

Why not actually hardware calibrate your monitor and have custom print profiles made? (After making sure you are using the correct print settings).

Monitor is hardware calibrated, printer is printing out ok just a couple of images are not quite right.

Situation 1: Grey's print slightly bluish, all other colours are fine

Maybe you're asking the printer to print colors which are outside of its color gamut. Not to insult, but you're softproofing to the correct printer/ink/paper profile? Experimented with different rendering intents? Viewing the dried prints under the same lighting conditions they'll be displayed under?

You are exhibiting what I call a symptom. I think most people go through this as they wrestle with color management. The gamut of your different equipment is different so you may see differences in color rendering simply due to that. Calibrate your monitor and have a custom profile made for your printer with the paper or papers you like to use.
That said
To lower blue just use curves to lower the blue or add/subtract yellow
To change red use curves to change red or add/subtract cyan
To change green use curves to change green or add/subtract magenta
You can use the above ideas to adjust skin tones by ratios
Reds look pretty rich in the second
There is a slight bluish tinge in the lighter areas of the gray

There's your problem. If you are using non-OEM inks you will never find an accurate free profile. Have a custom profile made.

Those images are essentially straight out of the camera. (5D2).
Granted the red is very strong in that second pic, the first one though I can't see the blue tint you describe.

Moving forward is there a simple way to duplicate a profile used by your printer, modify and rename it? As I'm not getting on with the Ilford profiles they supply for their paper.

I appreciate the advice given, thank you.

I tried that with the Spyder3print, 4 attempts and it fell over every time.
Reds all over the place, colours way over saturated.

Invest a few quid and have one made for you by a professional.

In the past, I had nothing but trouble with 3rd party inks. I don't use them anymore.
