Understanding Color Theory: Additive and Subtractive Mixing
Color Theory: Additive and Subtractive Mixing
Cone Classification
The cones in our eyes are classified into three types:
- Short-wave cones (blue)
- Medium-wave cones (green)
- Long-wave cones (red)
Additive Color Mixing (Light)
Additive synthesis is the mixing of colored lights. It’s called “additive” because the results are obtained by adding light to light. The sum of the three primary light colors (blue-violet, red-orange, and green) results in white light, the most luminous combination.
Mixing Primary Light

The Temple of San Pietro in Montorio
Cinquecento Architecture by Bramante (1502-1510)
The Temple of San Pietro in Montorio, located in one of the patios of the Franciscan convent in Rome (now the Academy of Spain in Rome), was commissioned by the Catholic Monarchs to commemorate the taking of Granada in 1492. It is believed to stand where Saint Peter was martyred. This work is considered a manifesto of Renaissance classicism due to its clean lines and decorative austerity.

Wreck-It Ralph: My name’s Ralph, and I’m a bad guy. Uh, let’s see… I’m nine feet tall, I weigh six hundred and forty-three pounds, got a bit of a temper on me. My passion level’s very near the surface, I guess, not gonna lie. Anyhoo, what else, uh… I’m a wrecker. I wreck things, professionally. I mean, I’m very good at what I do. Probably the best I know. Thing is, fixing’s the name of the game. Literally. Fix-It Felix Jr.
So yeah, naturally, the guy with the

Color Symbolism and Meaning
White
It is on the positive end of the gray scale and has a threshold value, brightness, and saturation. It is also value-neutral (no color). White can express peace, light, happiness, purity, innocence, children, divinity, harmony, and cleanliness.
Gray
It’s a neutral color that results from the combination of white and black. It symbolizes indecision and lack of energy and expresses doubt, melancholy, grief, boredom, and the past. When dominant, it creates an atmosphere

Plane and Solid Geometry
Plane Geometry
Plane geometry is the branch of geometry that deals with figures whose points all lie in a plane.
Types of Plane Geometry
- Descriptive geometry: Solves problems in the geometry of space by using operations in a plane and figures that represent solids.
- Projective geometry: Studies the projection of figures onto a plane.
- Analytic geometry: Studies figures using a coordinate system and methods of mathematical analysis.
Conic Sections
A conic section is the curve formed

Overview
Cuts are used in technical drawings to clarify the representation of an object by removing a portion. A section is the intersection of a cutting plane with the part (indicated in red). Sections are preferred over cuts as they offer a clearer and simpler representation.
Cuts are essential when the interior parts of an object need to be shown. The surface revealed by the cutting plane is called the cut surface. To create a cut:
- Determine the cutting plane, which should be parallel to the projection
