The pearlescent shell of a black-lip pearl oyster Pearlescence is an effect related to iridescence and has a similar cause. Structures within a surface cause light to be reflected back, but in the case of pearlescence some or most of the light is white, giving the object a pearl -like luster. [ 16 ]
A dark color, for example, forms a high contrast to the bright light spots and strengthens the effect. Favorable is also the use of a covering varnish in order to achieve an optimal effect. [4] [6] The pigments can be applied with all painting techniques established for conventional pearlescent and interference pigments.
Flakes with different colour effects may also be used within the same paint. [3] Pearlescent paint uses embedded pieces of iridescent material to produce subtly different colours depending on the angle and intensity of the light. More radical colour changes and "two-tone" or "flip" colours (e.g. from purple to orange) are sometimes produced.
Base coat used in automotive applications is commonly divided into three categories: solid, metallic, and pearlescent pigments. Solid paints have no sparkle effects except the color. This is the easiest type of paint to apply, and the most common type of paint for heavy transportation vehicles, construction equipment and aircraft.
