A white crayon too, white, an absence of all color.

😜

Technically, pure white is the absence of color. In other words, you can’t mix colors to create white. Therefore, white is the absence of color in the strictest sense of the definition.

What colors make black? What colors make white?

The way to create black or white depends on whether you’re working with an additive color model (light-based) or a subtractive color model (ink-based).

Additive colors combine to create white.

Light and electromagnetic radiation both create additive color. In this model of color theory, the combination of all colors creates the perception of white. You’ll also hear this model referred to as RGB, because when you work with additive color, you use red, green, and blue as primary colors. 

Digital color is additive.

Additive color is used in digital design, because computer screens show hues with colored light. Each pixel is composed of three tiny specks of phosphor, which emit red, green, or blue light when struck by an electron beam. When working with color digitally, like in Adobe Photoshop or Illustrator, your screen uses different combinations of these lights to create all the colors you see. So what is black on a screen? No lit phosphors.

Subtractive colors combine to create black.

The color of pigments and inks are subtractive. Subtractive colors are made of light that’s already passed through material. Painters can combine several colors to make what looks like black paint. Printing also uses subtractive colors; cyan (C), magenta (M), yellow (Y), and key or black (K) are the primary inks used. This is why printable files are called CMYK .

White reflects (light) of all colors, but white is not a color, hence black is also not a color but an amalgam of all the colors that are absorbed and are not reflected back.

  1. White is a combination of ALL colours, so in effect you are right, White is not A colour

  2. That’s fuckin funny!
    Every day I wonder why we’re at the top of the food chain.

  3. I found an abandoned military bunker and couldn’t figure out which branch it was. I found a pile of MREs and opened one. It had some food but the desert was crayons, so, Marines,
    I wish I could get into the Black/White debate. I sure don’t understand how it would be possible to mix blue,red,green, things Darker than white, and come back to white, but I’m unable to understand how anything that is a solid can be transparent.

  4. Black = no color
    White = all colors

    This was grade school stuff regurgitated in HS physics class.

    Or was until physics got Woke. Along with the Rainbow Coalition (Jesse Jackson) the gay crowd are perverting all the norms. The trick is on them. Hating white people would semantically mean hating all colors of people since white is all the colors of the rainbow combined. Take it from there……….

  5. white is all the colors of the rainbow

    Like I said, I’m not able to understand how atoms,made up of solid stuff with room between them can make a piece of glass, plastic, that is transparent. I’ve seen some four inch thick cubes of glass and even with all those atoms sticking together, you can still see right through it,, so obviously stuff does some unexpected things,, but by Golly I finally figured out that Colors thing.

    Take a prism and break up a beam of light and
    You get the colors of the Rainbow..

    Not All Colors..

    Now, if we analyze the wavelengths of the colors a prism makes and scientifically create paints,you spose mixing them together would make white?

    White light is able to be dissected into the frequencies that are found in white light. The colors of the Rainbow.
    White paint isn’t made of All colors..

    I had heard that said wrong enough it had me confused.

  6. I remember some years ago, there was some state that was about to pass a bill that mandated all government and legal documents must be printed on paper without color. The intent was that white paper had to be used, but fortunately somebody discovered that the bill would have actually required black paper to be used.

  7. Actually the difference between black and white is how they reflect colors. White will reflect all colors together and all colors individually. Black does not reflect any color, it absorbs them in simple terms.

    The colors we see are reflected light. The surfaces do not emit energy except in the infrared portion of the electromagnetic spectrum (think heat). Within IR there is no concept of color, just varying levels of heat.

    And, if the MRE had wallpaper paste for desert, it was USAF.

    • That is A difference.
      It doesn’t change the distinguishable frequency components Of white light.
      You are talking about Colors.
      White Light and its components that make it up is the topic.

  8. I have no scientific basis to argue from, but with my flawed understanding of light and color, I’m of the opinion that that black absorbs colors, but seems to absolutely gobble up green.

  9. ALL RIGHT, kiddies, enough bickering! Don’t make me come over there.

    I used to give the smart kids a question that made them scratch their heads:
    Why do TV screens use RGBK (the K is black), yet printing uses CYMK ??
    The answer (which took me about 5 years to realize) is simple, yet subtle:
    The first is emissive while the latter is reflective !!

    Like I said, subtle. Gotta know your spectral physics to understand all the ramifications…

    Any questions?
