The agent that glues pigments to the fiber surface.
What is Self Shade in Dyeing?
A textile colored using only one dye.
What is Visible Light?
Electromagnetic radiation (380-780 nm) visible to humans.
What is Electromagnetic Radiation?
Energy that travels in waves; includes visible light, X-rays, etc.
What is Wavelength?
Distance between wave crests; determines color in visible light.
What is a Nanometer (nm)?
One billionth of a meter; unit for measuring wavelengths.
What are Spectral Colors?
Colors produced by separating white light (prism/raindrop); ROY G BIV.
What are Non-spectral Colors?
All colors not found in the rainbow spectrum.
What are Achromatic Colors?
Black, white, and grays; lacking hue.

What is Color Fatigue?
Temporary impairment of color vision due to prolonged exposure to a color.
What is Reflection of light?
Light bouncing off an object; determines perceived color.
What is Absorption of light?
Light taken in by an object; results in less light being reflected.
What is Transmission of light?
Light passing through a material; can alter perceived color.
What is Infinite Thickness in Fabric?
Folding fabric to eliminate light transmission and evaluate true color.
What is Additive Color Mixing?
Mixing colored lights; primaries are red, blue, green. Mixing all three makes white.
What is Subtractive Color Mixing?
Mixing dyes/pigments; primaries are magenta, cyan, yellow (or practically red, blue, yellow). Mixing all three makes black.
