Color recognition

Metamerism

1. definition

Metamerism is the phenomenon wherein two colored samples will appear to be of the same shade under one light source but will appear to be different shades under a second source.

A phenomenon in which collars on both sides look the same in natural light (sunlight) as shown in the picture, but in artificial light (fluorescent light) they appear to be in the same color.

Hue circle

Primary colors

A color that cannot be created by mixing any other color.

Red, Yellow, Blue

Secondary color

A color that can be made by mixing two primary colors.

Orange, green, violet

Complementary colors

colors across from each other on a hue circle.

Complementary colors are pairs of colors which, when combined or mixed, cancel each other out (lose hue) by producing a grayscale color like white or black.

May cause Metamerism.

three elements of color

Hue : The name of the color itself, such as red, yellow, and blue, regardless of its intensity and color.

Value: Brightness and darkness of color.

Chroma : Clearness and turbidity of color

1. Solid Color verification Method

Check the hue, color direction, and chroma at an angle of 90°(face tone).

2. Metallic/Pearl Color verification Method

Check the hue, color direction, and chroma at an angle of 90°(face tone).

Check the side value and side hue at an angle of 45°(Flip tone).

3. a good way to color mixing
  • Due consideration before commencing work.(Color direction, Chroma, Value)
  • Always make color swatch and use the latest color swatch appropriately. (periodic updates)
  • Work accurately and cleanly.
  • Don't waste paint.
  • Use the scale clean.
  • Use a suitable can. (water-borne?, oil-based?)
  • Check the color of the correct light source and keep the light source clean.
  • Painting to cover up.
  • Follow the recommended operation methods and instructions.
4. Reason why color mixing.
  • Because the same model, the same color, can be different depending on the production plant.Because the car company uses color primer.
  • Because they do not completely cover up the paint after using a color primer.
  • Because color error between manufacturing dates of OEM paints
  • Because the manufacturers of OEM paints are different for the same color
