Is it possible to color blend in ZB ? like mix yellow with blue, you get green, etc…
?
I wasn’t able to get a very good blend using paint. Everything would get kind of brown or wouldn’t really blend. I had much better luck using colored lights. Here’s an example:
Three point lights were placed on a flat, white background. Each light had a primary color (red, green, blue). After rendering the brightness graph was edited to make the colors stand out. 
You can’t mix the paint directly because one will continue to overpaint the other, unless you use a transparent type material…
The way I blend my colours is to use the smudge brush to blend edges of different colours. Take a look at my recent post “I love Roses” I used 2 different colours of red and a dark grey and blended the edges with the smudge brush.
Maybe this isn’t what you had asked for but I hope it helps some!
interesting, but still the colors aren’t blended 100% correctly.
Wonder if its possible to make a Zscript brush that can blend colors. Would be very interesting.
This is actually a place where the Draw>Channels menu comes into play.
Try these steps:
<UL TYPE=SQUARE><LI>Fill the canvas with black
<LI>Select the Simple Brush and the color White
<LI>In the Draw>Channels menu turn the R,G or B channels on or off
<LI>Paint on the canvas
[/list]
Only the active channels (ON) will be affected.
I’d completely forgotten about those tools! Thanks Aurick.
Thank you aurick, I’ll have to take a look in a bit.
Didn’t Digits produce a colour blend script?
There are otherways…knowing your colours, and utilising different colour values etc.
I see Aurick’s come up with a better way… but I prepared this earlier today to demonstrate an alternative approach, so I’ll post it anyway in case it’s of interest. I hope at least in part it covers what you were asking.
The top row shows the three primary colours used.
First a vertical strip of yellow was put down with RGB only at 100% intensity, ZAdd on. Next a small blob of red was painted at the bottom using the same settings to show red + blue later. Then a red srtipe was applied across the upper part of the yellow strip. This was done with RGB only at 50% intensity and with ZAdd off. Finally a vertical strip of blue was added with the same settings as the last step.
As you can see, the results vary according to the brush used. The simple brush just overpaints with no blending. The Single Layer and the new Paint brushes give identical results in this context with the colours being blended. Obviously by varying the base colours and the percentages, different hues can be created. To produce more subtle colour gradients, use a low percentage and apply it repeatedly as required and/or apply the smudge, glow or hue shifter brushes as preferred.
Because the overpainting colours are being applied at less than 100% intensity, the shades above look a little washed out and pastel. However, this can be corrected selectively with various tools such as the saturatinon brush, the intensity brush, the shading enhancer, etc., or at a global level with the render adjustments. The following example was produced using exactly the same base colours as above, but here has been enhanced with a variety of pixol changer brushes, and I think you would have to agree, you can get them as bright and intense as you would like.
QuickLinks stuff!!! thanks for bringing that up, Rage and the great input, guys!
