primaarvärvi

Primaarvärvi, often translated as primary color, refers to a set of colors that can be mixed together to produce a range of other colors. These primary colors are considered fundamental because they cannot be created by mixing other colors. The specific set of primary colors depends on the color model being used.

In the subtractive color model, commonly used in pigments and printing, the primary colors are typically red, yellow, and blue (RYB). When light passes through pigments, the pigments absorb certain wavelengths of light and reflect others. Mixing these pigments results in a darker color because more light is absorbed. For example, mixing blue and yellow paint creates green, as blue absorbs red and yellow light, while yellow absorbs blue and violet light, leaving green light to be reflected.

In the additive color model, used for light sources like computer monitors and televisions, the primary colors are red, green, and blue (RGB). When light is emitted, mixing these colors produces lighter colors. For instance, mixing red and green light creates yellow light. The combination of all three additive primary colors at full intensity results in white light.

Understanding primary colors is crucial in fields such as art, design, and digital media, forming the basis for color theory and color mixing. The concept allows for the creation of a vast spectrum of hues from a limited palette.
