Ice T had a song out once called COLORS....but it really did not have anthing to do with painting.

A white pigment can be made into a very bright vibrant white by using a very small amount of violet,or indigo....and i mean a very small amount....but it's just that your eye's preceive it as a vibrant white when actually it's a very light purple.

Matching a color....that's when you get into the Blue color that is a red blue...not a green blue and so on....

How do you determine what compliments one another....like in a flower garden painting....the wrong color and the whole painting is screwed. Even as a kid coloring in books you would have this cool as shit coloring that you were so into and proud of...then bam.....that green you just used sucked big time.

even the black colour is a combination of the primaries.

depends on the color space.


Nice palette micose[/quote]

right, if i get what u said , its right...the 3 colours have to be perfectly equal in intensity , hard to explain wih my cheap english ...but the CMYK mode explains it all:
cmyk is additive light: no color=white, all colors=black
rgb is substractive light: no color=black, all colors=white

The main difference between PS and Paints on a pallet is that Photoshop mixes colours for light emission, where as paints arrange light via selective reflection vs absorption.

What this means is that.
The computer sees all the colours as white where as paints sees all the primary colors as brown

Q: Why not black?
A: Black is an absence of colour, but the paints are designed to reflect some colours, this means, if you mix Red and Blue the resulting colour will reflect partially red and partially blue the more dense the mix the more LIKE Purple it looks but its still technically Red and Blue (well 50% red reflected and 50% blue as the blue paint brings in some Red reflection and like wise for the Red. Which is why the colour get progressively darker but never perfectly black).

In summery; The paint has to absorb all the colours to appear black but mixes reflect some colours still, so to get a truly black paint you need a separate paint, Black. Same applies to White.

Q: How can I make PS paints added to the canvas act like real paint?
A: No you can't Unless you figure out a way that makes photoshop recognize absorption when you add colours.

- Seems negative? well yes the computers colour wheel is based on the monitors RBG which unfortunately instead of absorption (subtraction) this works on projection which is (addition).

Hence why the more colours you add the more closely you get to white (This is why the colour wheel has a white core and not a black one).

Multiply may be your best bet for mixing colours.

You would have to program the software to mix colours like a paint brush would.(selective absorption).


Other notes...

Art in one gallery will not look the same as another as the lights will effect what you see, same goes for monitors.

If you up the brightness in levels sometimes you can see easily where the clone stamp has been used. This is due to the persons colour profile obscuring the end result from view.

Thx for the complement of info great stuff Wiz and yes Nico, substractive, additive, i didnt went into it even if i thought of it ...cool adds! the "primaries" for painters like this circle u used is more like what i used for my "circle"....and these are the colours painter use for real ur right. Dew! this is deep my friend, cool to see a bit of "poetry" or "philosophiy" in this thread that really needed some hahahahaa! and what u talked about is instinct", which is a big part of all this shit.

Hey Marxman, im start to read ur add, looks good to me...still reading...

i must say its perfect mate, thats a point i wanted to speak about too. It s so much true! a program that would use the "chemical" (density, absorbption, permanence)properties of colours... and ...with odours btw next step in science of computers maybe! PHOTOSHOP v20..30..or more!

and for wht u said about MULTIPLY, thats what indeed i did to get this black with cmyk colours.u r right.
