How to choose CMY for moving head spot light?

Case Description


Will you pay much attention to the color when buying moving head spot lights?

As far as we know, color is a foundation of stage beauty,

as long as the color is appropriate ,

it can drive the atmosphere of the entire stage,

and create the tone of the entire event.

We know that the color of the moving head spot light,

the light source (maybe LED light source, or discharge light light source)

itself is white (similar, this is more accurate,

because each type of light source is white due to the color temperature

and other reasons.Maybe yellowish or even blue) light.

The color of the spot light is created through physical effects

to create different colors, and it shows different colors.

The color of traditional lights is almost the light coming out through the color wheel.

As shown in this photo, the color disc has glass sheets of multiple colors.

When a certain color of glass sheets overlap with the light beam,

the light emitted is colored light.

The human eye can distinguish 10 million colors in total,

but this is only an estimate, because the structure of

each human eye is different,

(Note 1: From

and the color that each person sees is also slightly different,

so the distinction between colors is quite subjective.

Here comes the problem.

Many times when we perform on stage,

we need a variety of colors,

and the color of the color wheel is limited (usually 5 to 14 colors),

then how can we get more colors ?

Thanks to the advancement of technology,

people discovered the principle of three primary colors and invented CMY.

What are the three primary colors?

The three primary colors are red, green and blue.

The three primary colors refer to the three most basic colors in colors,

and they can be used to blend into other basic colors.

That is, the basic color used to adjust other colors.

The color purity of the primary colors is the highest,

the purest and the most vivid. Most colors can be blended,

but other colors cannot be blended into three primary colors.

CMY stands for the process involves combining

varying amounts of cyan (C), magenta (M), yellow (Y),

ink to produce the full spectrum of color.

(Picture from,cyan%2C%20magenta%2C%20and%20yellow.

The CMY color model is a subtractive color model 

in which cyanmagenta and yellow pigments or dyes 

are added together in various ways to reproduce a broad array of colors.

The name of the model comes from the initials of

the three subtractive primary colors: cyan, magenta, and yellow.

The name of the model comes from the initials of the three subtractive

primary colors: cyan, magenta, and yellow.

CMY represents the most basic color,

which can be mixed into three colors of red, green and blue.

Furthermore, the three primary colors of red, green and blue are mixed with more colors.

So, in theory, CMY can mix a lot of colors

The same is true for CMY.

In theory, it can mix most of the colors.

The color of lights without CMY function has limitations,

CMY can meet different color needs as much as possible

Therefore, CMY is deeply loved by lighting engineers and stage designers.

There are two different CMY structures on the market.

One is the turntable type, which actually consists of several turntables,

The color of each turntable is composed of light to dark.

One of the characteristics of this kind of turntable CMY is its relatively low cost.

But the shortcomings are also obvious.

Is the mixed color relatively uniform?

(Rotate CMY color, mixtureis not very uniform)

Another kind of CMY, commonly known as "CMY system"

Because it is a number of different groups of glass,

The color obtained by superposition of glass designed by special craftsmanship.

The cost of this kind of CMY is relatively high.

And, the color mixing effect is very uniform

The color switching is very smooth.

Back to our topic,

If you choose a moving head spot light,

You should know how to choose the CMY, right?
