Once you know how to use complementary colours in your mixes you can get any colour you want. It's priceless information.
By the way, he mentions cadmium yellow and red - cadmium is highly toxic. If you want my advice you'll have nothing to do with it. Chromium is toxic too. There are good substitutes which are perfectly ok for us to use. Read the labels and avoid these heavy metals.
Also he mentions Prussian blue - a fantastic colour with the potential to stain EVERYTHING :shock: Use with caution.
Great site though.

Napthol Red and Arylamide Yellow are the ones to use instead of cadmium and chrome [chromium] Sometimes they're named that way on the tube [napthol and arylamide] You should check the ingredients on the label. Cheap brands won't list them - but then they won't use the more expensive cadmium and chromium, either. I still wouldn't want to eat them, of course.
Whenever you buy say Cadmium Red hue as written on the tube, you're NOT buying Cadmium Red proper. You're buying a substitute, such as Napthol Red. They can't say Cadmium Red if it contains no cadmium, so in effect they're calling it Cadmium Red colour.
I hope that's some help.

Even washing up liquid and household cleaners are subject to COSHH legislation and have MSDS's. Have a look at the contents of supermarket own brand hairspray, it will scare the heck out of you (but is quite good for sealing flock and pastel dust in place:lol:
If anyone ever has a concern go to google, type in the product name then +MSDS, eg Dettol +MSDS will lead you to something like this

Thanks for the information, guys. Most helpful to "painting virgins" like me. I've bookmarked this for future reference.
Is that course open to everyone Jeff or just for GWR man ?:shock::shock: - if so, I'd like to have a go at painting one. :lol::lol:
Interesting link Bob - it will be very useful to all I imagine.
