Colour matching on different media

[macman44]

I am getting strange (to me) colour effects when printing.  I am printing an image of old stonework onto cardstock, and depending on the stock I am seeing different colours. I have standard letter size bulk cardstock, and legal size Vellum Bristol white, and I need to match the colours.

•  In daylight, the legal vellum turns out slightly more green (but probably more realistic) and the standard cardstock has a distinct pinkish tinge (compared to what I see on the computer screen).

•  In fluorescent light (4000 K) it's the other way round, with the letter-sized cardstock looking greener and the vellum more pink.

 In both cases, the colour is a bit  washed out. compared to what I am seeing on the screen.

I know the whole subject of colour matching is quite complicated, and I know very little about it.  I also acknowledge that my 77-year old eyes aren't what they used to be.  But is there any reason why I am seeing this variation and the variation in the variation, and is there any way I can get both lots of printing to look the same, and look right?   The model on which the printed product will eventually be viewed will be illuminated with the fluorescent lights.

Because of the size of the images, and the high cost of the legal vellum, I'm sort of stuck with the two products.

The printer has a whole suite of print density settings (currently still at the default settings), and I wondered whether adjusting these might help.  But there are 16 separately adjustable settings, and just randomly playing with them sounds like an exercise in frustration:  are there any established techniques?

Is there anything else I can look at to understand what's happening and make a suitable adjustment?

The printer (Color Laserjet Pro M454dw) is fairly new, and has brand new toner cartridges.

Thanks for any insights.

Paul.
