Kleurteorie _
Wat is kleurteorie?
Kleurteorie is 'n menigte kategorieë, definisies en konsepte.
Hierdie tutoriaal dek die dele wat die nuttigste is vir webontwerp:
- Primêre, Sekondêre en Tersiêre Kleure
- Kleurwiele (RGB, CMY, RYB)
- Kleur Tint, Ligte en Versadiging
Die Kleur van Lig
Sir Isaac Newton het die teorie ontwikkel dat alle kleure mengsels van rooi , groen en blou lig is.
Dit het gelei tot die eerste bekende kleursirkel in 1666.
Die kleur van verf
In 1766 het die wetenskaplike Moses Harris die eerste kleurwiel geskep om Rooi , Geel en Blou as die primêre kleure te klassifiseer.
Moses Harris worked with paint (Newton worked with light) following a theory (by a French painter) that all colors are mixtures of Red, Yellow, and Blue pigments.
Color Systems
In this tutorial we will cover 3 different color systems:
- The color system used when producing colors by light (RGB)
- The color system used when printing (CMY)
- The color system used by artist and painters (RYB)
Printing actually uses a four ink color system.
CMYK: Cyan, Magenta, Yellow, and Key (black).
Primary Colors
Primary colors are the main colors in a given color system.
Primary colors can not be produced by mixing other colors a color system.
The primary colors for light are Red, Green, and Blue:
| RGB | Red | Green | Blue |
The primary colors for print are Cyan, Magenta, and Yellow:
| CMY | Cyan | Magenta | Yellow |
The primary colors for paint are Red, Yellow, and Blue:
| RYB | Red | Yellow | Blue |
Secondary Colors
Secondary colors are made by mixing two primary colors in a color system
There are 3 secondary colors in the color systems described here.
Mixing Light (RGB)
Secondary colors are Yellow, Cyan Magenta.
| Red | + | Green | = | Yellow |
| Green | + | Blue | = | Cyan |
| Blue | + | Red | = | Magenta |
Mixing Ink (CMY)
Secondary colors are Blue, Red, Green.
| Cyan | + | Magenta | = | Blue |
| Magenta | + | Yellow | = | Red |
| Yellow | + | Cyan | = | Green |
Note that mixing the primary colors of CMY produces the primary colors of light (RGB)
Mixing Paint (RYB)
Secondary colors are Orange, Green, Purple.
| Red | + | Yellow | = | Orange |
| Yellow | + | Blue | = | Green |
| Blue | + | Red | = | Purple |
Tertiary Colors
Tertiary colors are made by mixing one primary and one secondary color in a color system.
There are six named tertiary colors in RYB:
- Red-Orange
- Yellow-Orange
- Yellow-Green
- Blue-Green
- Blue-Purple
- Red-Purple
