LAB Color Mixing and You by fox-orian LAB Color Mixing and You by fox-orian
Unlike Perspective & Composition Part 3, however, here is a real tutorial today.

Ever wonder what LAB color sliders were in Photoshop? Here's a little bit of enlightenment to help you figure out what the hell they do.

A note about this tutorial: This is MIXING COLOR with LAB Sliders -- NOT speaking about the LAB Color Space which your open document can be converted to. You need special monitors that can show LAB color space -- something more useful to professional photographers. With LAB Sliders, you can use RGB and CMYK color space, both work just fine since we're using this for the purposes of choosing colors for painting/coloring -- NOT color correction.

Also: Adoption of the new "ORIANART" name. I believe I'm leaving the name Plastic Shards behind, soon.

Tnx that was valuable information.

Thanks for this helpful tutorial. Only just getting into colour theory! Still battling on the whole 'colour changes with temperature'. RGB sliders are pretty intuitive when you get the swing of it, but really you gotta know whats going on under the hood of 'why' rather than 'how'.

Question! When do we know which type of shadow to use? 
In your example. It's a warm light with warm shadow on the walls. ( unless I mistaken white for a warm light instead if a cool light) when does cool shadow come into play?

I'm not sure why I just started trying this two years after seeing this initially, but IT IS FUCKIN MAGIC. THANK YOU. SO MUCH.

I, personally, never liked the RGB sliders. I tried using Lab and felt confused so I developed around the HSB sliders. Thank for sharing this. I will give Lab another shot now that I understand it better and with the use of HSB the possibilities are endless =D

I've never really looked at the LAB setting before, but wow. It seems like a great deal of untapped potential and actually helps puts some color theory concepts into perspective. Thanks for this. :)

Thanks for the information!
I'll admit, I'm more interested in the CIE Lab color space because some papers in the Cognitive Sciences literature report stimuli colors in Lab coordinates for some experiments. Although this wasn't exactly geared towards someone with my interests, your explanation did give me some new insights into the Lab color space. Thank you very much for that!

This is interesting. I've never thought to touch these sliders, since I was so comfortable in HSB and didn't even know what LAB stood for. Thanks for explaining it so well and giving painters a reason to try it! :D

Each one of those tutorials are just great... belive it or not I'm learning a lot of color tricks with them... Thanx a lot.

Awesome tutorial, thanks so much for doing all these! I don't think I was even aware of this, or maybe I ignored it or something. You're doin a great job at demystifying photoshop :] +fav

Awesome! I did once guess the L must have been for lighting, but I never knew about the rest! This is a very good and helpful tutorial! Can't wait to practice with it! Thx!

Also, ORIANART sounds awesome.

ORIANART sounds so much better!

A little bit additional information: If you just choose the LAB in the "color" window, it's only a kind of fake color selector, your real colors are usually still RGB.
That doesn't matter though, if you just want to play around with color sliders to get creative!

To achieve true LAB colors you need to convert your document into LAB mode. However, your monitor is very likely not able to display the whole lab color space. Professional image editing monitors are needed.

YOU. HAVE CHANGED. MY LIIIIIFE! @O@ lately i've been trying to figure out how i can transfer what little knowledge i have about mixing oil paints to "mixing" paint in photoshop (especially for greys), and i was failing miserably! but then i read this tutorial and experimented a bit and was like "HOLY CRAP THIS IS SO BEAUTIFUUUULLL!!" i love LAB color sliders!
alexandergras Featured By Owner Jul 20, 2011
To me, a color picker must be intuitive in that it conforms to my real world experience of color. The Lab color space is easy to understand, but I find it extremely hard to plan what adjustments I have to make to the sliders to achieve the color I have in mind. I always need to play with the Lab sliders until I come close.

For painting, I find a HSV mixer (as the one in Painter) superior, because it behaves as traditional paint does, and if you understand the color circle, you'll know what to do to get the color you want. For example, in HSV complementary colors are immediately obvious, in Lab ... ? I wouldn't know how to find them there.

Since there is no useful color mixer in Photoshop, I built my own.

Excellent tutorial. Well explained and neatly layed out.
kvweber Featured By Owner Jul 20, 2011  Student Digital Artist
Nice! I had heard that this colour slider was used only for photo editing, so I ignored it for the past... however many years since Photoshop 7.0...BUT now I can see that there are some interesting benefits to using it. I'll have to try it next time I'm experimenting with colour. :D
NEOkeitaro Featured By Owner Jul 20, 2011  Professional Filmographer
Ha. I use LAB often in photography (it's seriously a life saver, sometimes), but I never thought illustrators would use it too. Now that I read it, it makes a lot of sense.

I still think it takes a photoshop geek like you to consider using it in the first place though :p
AyameSuzuki Featured By Owner Jul 20, 2011  Hobbyist General Artist
Thank you for all the tutorials, I don't think this one will be useful to me (perhaps it will) but it is really nice that someone of your talent is putting out helpful things.
tofuburgers Featured By Owner Jul 20, 2011
Great tutorial, thanks so much for sharing! :)
fadeddreamss Featured By Owner Jul 20, 2011  Student General Artist
Thank you very much for your tutorials! The last one wasn't complete, but already have some precious information! As for this one, I've never used LAB before, but I was "ooooh" hrough the reading, because it's so cool! Since I'm learning photography too, I could really relate! Will try that in my next illustration!

great works
Dualmask Featured By Owner Jul 20, 2011  Professional Digital Artist
Tasty new knowledge. I tried using the lab sliders a few times, even though I didn't quite get how they worked. This should help...even though putting it to practical use in my work will be a whole different adventure altogether.
Localized Featured By Owner Jul 20, 2011  Hobbyist Digital Artist
Thanks for explaining this. I've heard you mention LAB previously various times, but I haven't tried it that much. I'll be sure to do so now. The achievement unlocked part made me chuckle :D

I was going to make a point about how you somehow can have a greenish-magenta or yellowish-blue, but it seems this is only true for yellow-blue and red-blue. Though perceiving a colour like yellow-blue would only occur under special conditions so it's irrelevant for the most part. Here's a Wikipedia article on the subject: [link]

And leaving behind Plastic Shards :ohnoes: !? But I like PS, whatever works for you though.
