Perusväreistä

Perusväreistä refers to the concept of primary colors in color theory. These are colors that cannot be created by mixing other colors. In subtractive color mixing, such as with pigments or paints, the primary colors are typically red, yellow, and blue (RYB). When these colors are mixed, they absorb certain wavelengths of light and reflect others. For example, mixing yellow and blue pigments results in green because the yellow pigment absorbs blue and red light, while the blue pigment absorbs red and green light. The remaining reflected light is green.

In additive color mixing, which applies to light, such as on computer screens or televisions, the primary colors are red, green, and blue (RGB). These colors are emitted by light sources, and when combined, they create other colors. Mixing red and green light produces yellow, while mixing all three primary colors of light at full intensity results in white. The absence of any light is black.

Historically, the RYB model was the primary focus in art and pigment-based applications. The RGB model became significant with the advent of technologies involving light emission. Understanding primary colors is fundamental to comprehending how colors are perceived and how they interact in various media, from painting to digital displays. The choice of primary colors depends on the context of the color mixing process being discussed.
