Gelbfarbe

Gelbfarbe, also known as yellow color, is one of the three primary colors in subtractive color mixing, alongside cyan and magenta. In additive color mixing, used for light, yellow is produced by combining red and green light. It is perceived by the human eye when light with a wavelength between approximately 570 and 590 nanometers stimulates the cone cells in the retina.

Historically, yellow pigments were derived from natural sources such as ochre, saffron, and certain plant dyes. These natural pigments often offered a range of hues from pale lemon to deep goldenrod. In modern times, synthetic yellow pigments and dyes are widely used in paints, inks, textiles, and plastics, providing a stable and vibrant palette.

The psychological and cultural associations with yellow are diverse. It is often linked to happiness, warmth, optimism, and sunshine. However, it can also symbolize caution, cowardice, or even illness in some contexts. In art, yellow has been employed to evoke a sense of light, energy, and vibrancy, with artists like Vincent van Gogh famously utilizing its intensity in his works. Its presence in nature, from sunflowers to ripe wheat, further cements its association with life and abundance.
