Love this thread. Love those spacey galaxy blends by maxxev earlier.
I've been making more crazy skinner blends...
Guess what colour this 'pattern sheet' will make?? Dont cheat, guess..!
Tertiaries!! The small blobs in the middle were mixed by hand first and as you can see the skinner blend came out the same . Now i know its not the nicest or best blend in the world but the point is it managed to produce the desired results.
Next are some shots of the sheet mid blend. Because the blend is done using the base colour channels many different colours come through as the primaries start to mix. All the horrid yellow blotches in the first one are from the clay sticking to the pasta machine. If you take your time and avoid the blotches the half mixed blends can look quite nice. (honestly)
And finally all the different patterns below (i call them patters) will result in exactly the same blend as they all use exactly the same proportions.
Ok, no need to read the next bit unless you want a headache...
The point of all this is to have independent control of each colour channel in the mix so that you can introduce a blue, say, at one very slow rate, while having the white kick in really quickly. I noticed that if you blend a dark colour into a light colour the dark will come in really abruptly. So a blend from black to white will start white and then all of a sudden be much darker. It seems to do this even with a very, very thin sliver of black and loads of translucent*.
This way (once the method has been perfected) I think I can get much more gradual blend. Also, and this is the main point, I can have nonlinear graduations of multiple channels!!!
It's hard for me to explain but basically you can have a blend from yellow to blue, passing through green, blending at one rate (linear). And then also have a white channel to mute parts that is being introduced at a different rate (non-linear). So you can have zero white in the blue. Then gradually add loads of white as it passes into green. When it hits green have very little white. Remove all white as it blends into yellow. And then re-introduce the white again for a very pale yellow at the end. Impossible to do if you just blend the pre-mixed colours. If that makes any sense? Basically control of each colour channel for a non-linear blend. I'm writing it all up to put on a web site but don't even have a site yet so will be a while before that happens.
If you want a better description of what I mean by non-linear blends (and an even bigger headache) you could read post 16 of this thread from Physics Forum where i got a few diagrams to help explain. http://www.physicsforums.com/showthread.php?t=427246
Warning though: my explanation of things are pretty confusing and I got a couple of complaints saying it was hard to follow. But I'll lay it all out in easy to follow steps one day. The guy that helped me on that site understood perfectly though and brought up a really good point.. Is there really any benefit to this method? Well the more i play with it the more I think that maybe there is. Really the proof is in the pudding so i'll have to make some spectacular blends once I've nailed the process.
Dont worry if your . I am too
*I have also noticed that mixing translucent in to de-saturate the colours is less effective than getting the proportions correct. If you mix allot of translucent into the black, and then blend the black into the white, the resulting gray has just as much translucent in it.
I.e mixing trans with the black is also mixing trans with the white. You end up desaturating all the colours. Even the white. Better to get the proportions right in the first place. That said, using translucent does help.
