Orange (colour) and political activities, with the colour orange being associated with Protestantism similar to the Netherlands. In optics, orange is the colour seen by the eye when looking at light with a wavelength between approximately 585–620 nm. It has a hue of 30° in HSV colour space. In the traditional colour wheel used by painters, orange is the range of colours between red and yellow, and painters can obtain orange simply by mixing red and yellow in various proportions; however these colours are never as vivid as a pure orange pigment. In the RGB colour model (the system used to create
Alumina effect pigment applied to the pigment particles to adjust them to solvent-based and water-based coating systems. The pigments can be used in combination with many conventional pigments as well as with other effect pigments. Nearly unlimited styling possibilities are the result of these combinations. Alumina effect pigment An alumina effect pigment is a pearlescent pigment based on alumina (aluminium oxide). In the first step of the production process, AlO (Aluminium oxide) flakes with a very smooth surface are formed. The flakes are produced using a crystal growth process. They are formed in the corundum structure (α-AlO). The desired flake shape is achieved
