Color Theory

Step 1: Understand the origin of the color wheel. The concept of a color wheel originates from the scientific study of light and its spectrum.
Step 2: Identify the key contribution of Isaac Newton. In 1666, Sir Isaac Newton conducted experiments with a prism, demonstrating that pure white light is composed of a spectrum of colors.
Step 3: Connect Newton's discovery to the color wheel. Newton arranged these spectral colors—red, orange, yellow, green, blue, indigo, and violet—into a circular diagram. This was the first color wheel, created to show the relationships between colors. While others like Goethe and Chevreul later developed more complex theories and wheels based on psychology and perception, Newton's was the foundational scientific model.

Step 1: Define additive color theory. The additive color model describes how light produces color. It is used in digital displays like monitors and televisions. The primary colors in this system are Red, Green, and Blue (RGB).
Step 2: Understand how secondary colors are formed. In the additive model, colors are created by adding light. When two primary colors of light are mixed, they produce a secondary color.
Step 3: Apply the rule for Red and Green. The mixing of red light and green light in equal intensity produces yellow light. The full set of combinations is:

Red + Green = Yellow
Red + Blue = Magenta
Green + Blue = Cyan
Red + Green + Blue = White

Step 1: Define subtractive color theory. The subtractive color model describes how color is produced when light is reflected off a surface and some wavelengths are absorbed (subtracted). This system applies to physical media like inks, dyes, and paints.

Step 2: Identify the primary colors of the subtractive system. The primary colors are Cyan, Magenta, and Yellow (CMY). In printing, Black (K for Key) is often added for depth and convenience, creating the CMYK model.

Step 3: Differentiate from the additive system. The additive primaries (Red, Green, Blue) are used for light emission. The subtractive primaries (Cyan, Magenta, Yellow) are the secondary colors of the additive system and are used for light absorption/reflection.

Step 1: Understand Additive Color Theory. This theory applies to emitted light, where colors are created by adding different wavelengths of light together. This is the principle used by electronic displays like TVs, computer monitors, and phone screens.
Step 2: Identify the primary colors of the additive model. The primary colors of light are Red, Green, and Blue (RGB). When all three are combined at full intensity, they produce white light.
Step 3: Differentiate from other color models.

CMYK is the subtractive color model, used for printing with ink.
RYB is the traditional color model used by artists for mixing pigments.
OGV (Orange, Green, Violet) are the secondary colors in the RYB model.
Since the question specifically mentions television monitors, the correct model is RGB.

Step 1: Understand additive colour mixing. This system applies to mixing light, not pigment. The primary colors of additive light are Red, Green, and Blue (RGB).
Step 2: Recall the combinations of additive primaries.

Red + Green light = Yellow light
Red + Blue light = Magenta light
Blue + Green light = Cyan light
Red + Green + Blue light = White light
Therefore, the combination of blue and green light produces cyan.
