If you are mixing colours, you have to be clear if you are mixing lights or pigments/paints.

If you are mixing lights, you get more light, so this is called additive mixing of colour. You do this by shining different coloured lights on to a screen.You need blue, green, and red light to make white light. Red, green and blue are the additive primary colours because none of them can be made by mixing other colours.

If you are mixing paints, this is subtractive, because paints work by absorbing light, so if you have more than one, more light is absorbed and less is reflected to the eye. The idea of the subtractive primary colours of red, yellow and blue is used in art rather than science. In science we would define them as cyan, magenta and yellow.

Some primary colors, such as red, green, and blue, are called additive because they are used in additive color mixing. In additive color mixing, different combinations of these primary colors are added together to produce various colors. For example, adding red and blue light together creates magenta, green and blue light creates cyan, and all three primary colors combined create white light. This is the basis for how colors are produced on electronic screens and displays.

Are there 3 or 4 primary colors?

There are generally considered to be three primary colors: red, blue, and yellow. These colors cannot be created by mixing other colors together. However, some people may argue that there are four primary colors when including cyan as a primary color, especially in the context of additive color mixing (like in digital displays).


What number do you add when using the additive identity?

Zero. It's called the "additive identity" because when you add 0 to some number you always end up with the same number, like 17 + 0 = 17.


What are some known facts about the number zero?

It is the additive identity of most sets of "ordinary" numbers. Division by zero is not defined.


What colors does tasc call?

SOME COLORS REQUIRE A SPECIFIC AMOUNT OF DAYS TO PASS BEFORE BEING CALLED AGAIN.. UNLIKE "PINE and SAGE" WHICH ARE CALLED ALMOST DAILY. THESE "GROUPS" OF COLORS WILL VARY SLIGHTLY AS DAYS PASS, NEW COLORS BEING ADDED THE ONES CALLED BEING REMOVED. EXCEPT SAGE AND PINE OF COURSE AND PROBABLY A COUPLE OF OTHERS. WITHIN THE 30 DAY PERIOD ALL THE COLORS LISTED WILL BE CALLED AND THE PROCESS STARTS OVER....OR IS NEVER ENDING DEPENDING ON HOW YOU LOOK AT IT. SO SAY A COLOR WHICH WILL TEST WEEKLY COULD BE CALLED ON A FRIDAY AND AGAIN THE FOLLOWING MONDAY.....TUFF SYSTEM TO BEAT I KNOW IM ON COLORS BEEN DOING IT FOR YEARS.. I HAVE NOTICED THE QUALITY OF LIFE IS BETTER WHEN IM CLEAN....NOT MUCH MINE YOU BUT NOTICEABLE.....SO TRY YOUR BEST, JUMP THROUGH THE HOOPS,AND BECOME THE SOUL RULER OF YOUR DOMAIN AGAIN.............JAK.


Are black and white colours or are they shades?

they are achromatic colors because they have no hue?and even though some people may tell you that white is the presents of all color and black is the absentsif you mix the primary colors (Red Yellow and blue) you will get whitebut what most people forget if you mix the complementary colors (cyan , magenta and yellow) you get blackironic isnt it you mix the 3 opposite colors to white and you get the complete opposite to white (black).they are not classed as normal colors however because you can not make any new colors out of black and white on there own.but if you mix them with other colors white acts as a tint and brightens the color (makes red into pink) and black acts like a shade and makes the color darker (makes pink into red).so half the colors that exist today would never of existed if the achromatic colors did not exist.
