I don't get color theory.
I understand values and black & white ranges, but when it comes to translate that into color it makes absolutely no sense.

How the fuck do color shadows and lights work?

>> No.3242367

>>3242362
You should be posting in the question thread, for one.

Secondly, if you're not understanding how light and shadow works with color, you need to take a step back from color and work on values until they are solid. Value is the first part of color that you learn, the second part is hue/saturation.

Can't blame you for being frustrated and confused. If you take the advice then awesome and if not then good luck to you, you are someone who wants to learn the hard way.

Realize saturation looks like shit, dial it back, focus on colors that look good together when you want them to and bad together when you don't. Always desaturate more than you think you need to. It's better to deceive the eye with contrast than to actually have violent saturation.

Draw or paint still life in greyscale. Get your values and forms down first. Then guess what? You do still life in color next.

Here's a tip for you that will help immensely: Always lay down your background tones/colors first before you get to the subject. Colors and tones are all relative to each other, so this helps you ensure you are seeing everything correctly.

Good luck

Apply the same thing to hues. Go from the darkest hue, by adding black, to the lightest version of that hue, by adding white. Then do the same with colors, like making red darker by adding blue, or green.
Color theory is not something that can be taught here. Pick up some books on it, watch YouTube videos. Most of color theory in practical application is mixing colors, knowing how to cool or warm up colors, and knowing how they interact with each other.

Color and Light by James Gurney

Your welcome

>> No.3246587

really quick and probably completely wrong:

palettes should be mixed based on lightness/vibrance of a colour and how close it looks to your base

eg. say you're painting something with a base of violet, you should be focusing on pinkafying it with the highlights and purple-bluing it with the shadows

more or less with a colour wheel the colour next to yours clockwise should be the base of your highlights and counter-clockwise your shadows for simple aesthetic

obviously this only really applies under certain circumstances and as I said I'm probably fairly wrong

We'll start with the basics of color.
You have..

Hue: The closest pure color that matches up with the color you have at hand.

Value( or lightness): How light or dark a color, literally a scale between white or black.

Chroma(or saturation): A measure of how close that color is to neutral grey or the strongest hue possible for that color.

These are generally how you will measure color.

The photo I linked shows you the entire color spectrum in a 3d model.

Up and down gives you lightness.
From the center, and towards the center gives you Chroma.
Hue is a bit hard to see, but if you imagine viewing it from the top. The central axis revolves to determine hue.

All the colors you'd be able to use are in this 3d model of color.

If you are a digital artist, you probably are only concerned with sRGB.

Which has Red, Green, and Blue on a scale from 0 to 255.

Generally, if you have a color that needs darkened because it is receiving less light, you would move towards black on your Munsell sheet. If you need a brighter color, you would move away from black on your Munsell sheet.

Basically everything will reflect light in a similar manor, but it may appear different based on the surface.

For example, if you have polished metal, it will reflect your surroundings in a warped manor.

If you have wet things or the above picture, it will usually have some sort of highlight.

Variations exist.

If you are observant, which I know you aren't, you'll notice (in the picture that describes moving away from black in a radial pattern) that the brightest version of a single color is not brighter than white.
In most pictures that require it to be brighter, a little white is mixed in.
Be cognizant of this.

Lower the two suns down to zero to eliminate direct light.

Since light is reflected from our atmosphere, most pictures will have a little ambient light.

If you notice, there is a bit of ambient occlusion on the bottom.

Notice also that there are two shadows.

The most effective way to show volume is to create a value change.

The most basic render is a single light source with changes in value.

The more light that reflects off the surface of an object, the brighter it will become.

The less light, the dimmer it will become.

Here are a few things that you need to work out.

I want you to look through them, and really study them.

Then take a walk, and look around for them in your environment.

can you explain this in more detail, I'm not very sure what you mean, are you referring to adding white in the middle of some color to show that it is emiting light?

>> No.3247962

>>3247930
I realize rereading that I wasn't quite lucid at the time.

Disregard that.

Most electric lights emit a slightly off white light, and I think I was confusing something.

The gist of it was that each color has it's own maximum value.

This gets distorted in HSV/HSL by lumping lightness/value at a fixed value for the highest saturation.

The real 3d color space is a bit lopsided, and not at all a hexcone or double hexcone.

Something like this >>3245440

Notice the highest chroma for each color is not at 5 or 10.

Some colors are naturally brighter than others.

If you need to exaggerate brightness, it becomes more necessary to add in white.

------------------------------------------------------------
Unrelated to above.
Pic related.

Something I noticed earlier that might not be noticeable at first glance is that the light in most settings is white.

So the color on a surface form changes not just because it's reflecting less light of its own color, but because near the lightest point it's reflecting some white light too.
I'm not talking about a highlight.
This is basically true for every material, and it's worthy to note because it changes the saturation, and hue of the color ever so slightly in addition to value.

>This gets distorted in HSV/HSL by lumping lightness/value at a fixed value for the highest saturation.
Can you explain more about this? I often hear it's important to lay down your values correctly but how does that work with colors having their own maximum value that isn't a actual number value?

I wouldn't obsess over this.
The Lab color system seems to be the best a determining value.
If you have photoshop there's a little slider that will give you the true Lightness of the color you want to use.
Lightness is fairly equal to Value.
From what I've seen on a scale from 0-10

Red~#FF0000~5
Yellow~#FFFF00~9.5
Green~#00FF00~9
Cyan~#00FFFF~9
Blue~#0000FF~3
Magenta~#FF00FF~6

It's probably best to just feel it out though.

eh this kinda works but what they misunderstand is that as soon as you make the pastel tones you have already desaturated your pallete by at least a whole level mixing in general desaturates is something people need to realize

I'll try simplifying or destroying this explanation

a colors chroma is how true its color is
some true colors are inherently not very bright
birghtness, tint and saturation relate to how much color to white and black are mixed with a color
in every instance of mixing a color will lose a little chroma but if the colors are lighter or white is used it could get lighter
that is why you never really think of yellow mixed with black as yellow even thou you can do that
It is because so much of yellow chroma is mixed away so quickly we rarely think of something as dark yellow without surrounding color to compare it to
Its also why purple mixed with white even if it is lighter isn't necessarily considered a rich color.

>> No.3250749

>>3250737
you kinda are choosing the scale use by making a pallete, the trick there would be to mix then find more chroma heavy colors closer to the new pastel tones. It is actually okay to use desaturated colors and important to making the bright colors work, mostly just take the extra step to choose some really bright colors from the pastel pallete and make a new pallete based on those colors instead. Otherwise you essentially made a less saturated pallete out of primary colors.

lab is my favorite too, it's nice changing the actual luminosity instead of think about about two or three things for every change in value
