Okay, so here we have Ultra Ream Blue and a Thar Label Blue with a green bias. So just to give you a quick indication of their biases, we'll do as we've done before and just add a little bit of white. So now you can instantly see because this has got a green bias to it, if we mix it with the red, this undertone of green will act as the red's complement and as we've learnt that complementary colours mute each other out. So if we have the red and this blue, we're not going to be able to get a really really bright purple because the complementary colours of the green and the red will neutralise each other. So you can see the big difference here in how bright the green is. So you can see the big difference here in how bright this one is in comparison to the other blue. So as you can see a red-based blue mixed with the blue-based pink or blue-based red, it's always going to mix the brightest purple. So the key three points to remember are one which red you're using, two which blue you're using and three which are how much white you're using because this can alter the hue of your colour. So you can see how terrible this is to make a purple, like it's really a really kind of nasty colour, no way in comparison to this real nice brightness that we've got over here. So now let's have a look to see if you went even further the wrong way and we're using the soft thalio blue with the green bars with the cadaret. So still red, bright red, still a blue, we know this can get a really bright blue but it doesn't make purple when we mix them together. In fact it's very very close to a grey. So you do, I still know you. Well I'm over being sad now, but going back to the old me, I'm over. Whilst I'm in the past when it kinda sucked anyway, we could be vegetarian meal and we could listen to a day to remember of all of the sweet. You know the E E E and there's so many reasons that everything could fall apart but it never did. So the other way to have a bright purple is a bright pre-mixed purple. This is cobalt violet. You can start to see when you're looking to the labelling what is made of. So it's got quinacridone which is this colour here. We've got a zinc white and a dioxide purple as well. So you can see already it's a lot closer if you're trying to make a clean purple. So this is just with the white. You can see how slightly more vibrant than this one. You know not really, it's very very close. I mean it's got a slight more punch but this is very very close. Okay this is Wilkamp from Wilkamp Art School.
