Why won't blue and yellow turn into a bright green with digital?
>>
>>7828483
it's green but neutral
>>
Because digital art is not real art
>>
because the colours are not real
they rgb led lights dot matrix or something

You'd need a software that emulates traditional subtractive mixing to mix yellow and blue to get green. Digital programs just take the average between yellow(255,255,0) and blue (0,0,255) and gives you (127,127,127) or a muddy grey. Linear interpolation blah blah retarded shit that doesn't matter. Just use a program that simulates traditional or use CMYK and mix cyan and yellow instead.

>mfw the coders fucked it up but it worked well enough for long enough that it is everywhere and no one bothers fixing it

LOL
Imagine using software so shit that it gets mogged by FOSS that hasn’t gotten updates in years
>>
>>7828897
That's Cyan Yellow and Magenta though. You don't need advanced software to mix those

Yeah sure buddy. Try it on your program and see what happens.

And then here is Red, Yellow, Blue.

I assume since your files are named spectral you know what you're talking about. CYMK isn't true mixing, but it does approximate subtractive mixing well enough for most programs just because of how they're set up to average colors.

Spectral mixing is however, the closest you can get to traditional mixing on digital because of how it works around wavelength reflectance.

When you mix all the primary pigments, they get darker (subtractive mixing).
When you mix the digital primary colors, they get brigther (additive mixing).

They are different systems.

Now, the reason why yellow and blue will give you grey on PC. The PC just calculates an average for performance reasons. Fully opposite colors have grey in the middle.

Until now, I think that the only way to simulate real color mixing is with the plugin Mixbox (which was created by considering the performance too), which I think is already implemented in Rebelle, and maybe it is implemented in Krita too.

I would maybe debate on whether there’s any actual difference between RGB and CMYK. It’s just a numeric choice, like putting your phone in the pocket top down or top up. Both depend on tristimulus nature of human eye, look at respective spectrograms to perhaps see what I’m getting at with this.
The problem with digital paint is that after any mixing is done it is stored back as three values and it immediately ‘forgets’ what kind of pigments composed a color. Maybe it’s not that major, I’d have to do some thinking on this one.
>>
>>7829330
Ye ur right. In most digital art software there isn’t a difference between RGB and CMYK when it comes to mixing. Almost all painting programs process color internally in RGB.

CMYK is used for print because it matches the physical constraints of ink on paper, so it’s more accurate for predicting printed results than RGB, but digitally it still doesn’t behave like real paint. Mixing is usually channel based interpolation rather than pigment interaction, so even if CMYK works closer to trad, it'd still make painting and mixing convoluted af lmao.

Spectral or pigment based mixing is the closest digital equivalent to traditional paint, since it models colors as wavelength curves (how our eyes see color) and mixes them multiplicatively, only converting to RGB after the fact when its time to display them. That’s more computationally complex and harder to integrate into standard workflows, which is why most trad programs like Corel Painter or Rebelle use physically inspired spectral approximations rather than true spectral computation.

All this to say, if you wanna mix colors just use a program like Rebelle or Corel lmao.

>>7829339
Or MyPaint. If you only care about painting it is perfect.
Is it ignored by people only because it has no editing features?
>>
>>7829347
Hm, never heard of it, looks like it's abandonware and was mostly used by linux users. The same search shows that apparently Krita integrated its brush engine so that's probably why it was abandoned. I don't really use or like Krita, but I'm always impressed with just how much their program can do. Reminds me a lot of blender with how modular it can be.
>>
>>7829351
Abandonware or not, the few features it has work very well. I’m not gonna lose sleep over not being able to receive email with it.
>>
>>7829293
>Spectral mixing is however, the closest you can get to traditional mixing on digital
it's not any closer than mixbox, both just kinda wing it in places
mixbox might actually be closer for most purposes
>>
>>7828483
because my laptop isnt fast enough to run perceptual mixing at 8k
