someone red-pill me on RGB

is there a difference in digitally painting with RGB vs CMYK/LAB etc. as the colour profile?

>RGB - color light. Digital-only images.

>CMYK - color pigment. For when you want to print your shit.

Use CMYK only when you want to make a printed image.

Pixels are red, green and blue. Printer ink is cyan, magenta and yellow.

[Anonymous No.3502642]

>>3502637
no, depending on the software it might have some effect with like blending modes and things like that but it doesn't change anything intrinsically. not for painting anyway, for advanced printing stuff only printers care about it may do.

I guess you're referring to the old thread about lab painting, and how zeen and other chinks apparently use it to create such pieces. Idk buddy, have you tried it?

big issue in Lab that, things not working, i have to use the Lab sliders in RGB colorspace. not that it matters really, but for symmeties sake it's slightly annoying, lol

>is there a difference in digitally painting with RGB vs CMYK/LAB etc. as the colour profile?
Not anything that your pathethic human eye can detect. There is more different in colour from one monitor to the next, than there is between a CMYK image and a LAB one.

>>3502640
>Use CMYK only when you want to make a printed image.

Not really, today most printers automatically convert to CMYK, and the point of CMYK of "it looks in the screen the same that it will look printed" doesnt work anyway, because most printers print diferently anyway.
It's easier to just adjust an RGB image for printing than it is to make a dull looking CMYK image look prettier for screens.

The "oh but the colorspace is different" is just a matter of taste and you are deluding yourselves if you think that having a pallete in a different display will better your color use.

If you're in lab you'll need to convert to srgb before saving/exporting it as that's what people will see when you post online. Lab allows for some great photo-retouching capabilities because of how the channels split but it's just another tool. You should look up color spaces to understand more. Your monitor probably might not even display Lab colors properly. If you ever wonder why your posted work doesn't look like it did in the editor, it's because when you saved it there was an implied conversion to srgb that dulled it.

For painting, you still have to know a lot of color theory whether you're using hs*, rgb, cmyk, or lab sliders. Look up Linran's tutorial to understand rgb, this is a good starting point for Lab https://www.deviantart.com/fox-orian/art/LAB-Color-Mixing-and-You-243642090 , and David Hornung's Color book has a chapter at the end for CMYK/computer color (in addition to being a very good book you should read anyway). Learn them all as they are just tools and not a panacea.

RGB is additive and is used for display on screens, CMYK subtractive and is for print. The difference is subtle but reds and blues are going to be less vibrant when working in CMYK. Similar limitations in the yellows and magentas occur in RGB.

in photoshop for example you don't get 5 or so blending modes including color dodge, and nothing in the filter gallery (maybe you do in CC if Lab is gaining in popularity though idk)

this post almost made me throw up. goes to show how some digifags are so far up their asses about digital painting that its not even funny anymore.

you realize there are other ways to tone down colors right? why would people waste their time to make a layer or have a layer mode on brush to just tone something down? this is why opacity exists for glazing colors on top, that is how fucking craig mullins and any other respected digital masters paint, with fucking opacity.

SAI doesn't have different color modes but it has better and smoother color blending than photoshop (along with some other nice features that adobe's only recently caught onto like line stabilization and being able to pan the fucking canvas). Worth giving a go for those reasons.

No one said not to use RGB, just that digital blending kills saturation (which has to do with it dealing with color averages and not pigment), and like I said in my post above if you're aware of this you'll find a workaround for this problem. Most people use overlay and dodge modes for it. However these posts don't disprove that Lab can be a useful color mode to work in, if that's what you're trying to prove.

>>3504587
OK there is one specific condition where you don't lose saturation and that's if your base colors are at 100% saturation, in the far right of the color picker field. If you open pic related and use the color picker, you will see that in the second example where the colors are not at 100% but still quite saturated there is a drop off in saturation in the midtone. Now compare this with mixing pigmented paint like oils in real life (or just post more smug reaction images).

Based Ruan has to use RGB color space because he's painting on sub-pixel level creating illusions of colors that human eyes is physically incapable of seeing via jpeg artifacts. RJ doesn't paint, he's sculpting with photons so he has to use the same color mode as our eyes and displays.

finding next to nothing on painting in Lab mode which leads me to believe it must have some pretty obvious pitfalls, or else more people would use it right? I’m going to try to paint a full piece not just play around with a few hues to get a notion of the issues (besides the obvious ones that arent enough to turn me off from investigating).

Really think there has to be some fatal flaws because not even the shittiest youtube artists try to give Lab mode as a le protip for le dynamic colors (lab sliders are different and a fairly common tool, and usually not used by begs)
