☆Approximate color advancingcolour
When a color and its complementary color are placed adjacent to each other on the same plane, the human eye looks closer than its complementary color. Colors ranging from yellow-green to bright red are colors with this characteristic.
☆Bright color; eye-catching color assertivecolour
A color that attracts or provokes attention because of its relatively bright or high saturation.
☆Add blue and white blueing
Offsets the yellow tint of some white paints or lacquers by adding trace amounts of blue, thereby increasing their apparent whiteness.
☆Multi-color brokencolour
Composite polychromatic effects result from the self-melting of wet paints of various colors, or by skilful manipulations that produce irregular effects.
☆Chroma; chromaticity
The color quality of a color stimulus value that can be determined from its chromaticity coordinates or from the combination of its dominant or complementary wavelength and its stimulus purity.
The International Commission on Illumination system CIEsystem is a chromaticity system formulated by the International Commission on Illumination, which uses the tristimulus values X, Y and Z required to match the color to determine the number of three reference primary colors X, Y and Z.
☆Colorimeter Colorimeter
A device for measuring color. Existing Colorimeters include tristimulus Colorimeters, which use color filters to simulate ternary visible reference colors, and Spectrophotometer s, which measure color reflectance across the visible spectrum (typically filters with narrowband filters). light Spectrophotometer ). Both can provide direct readout of various forms of tristimulus value data.
☆color color
The apparent quality of a surface can be characterized by its hue, saturation, and lightness.
☆color coordinate value colourcoordinates
表征某颜色在所有颜色的三维图中位置的数字值。在1931年的CIE体系中，色座标值是X、Y、Z三刺激值或Y值和色品座标值x和y。以后的体系（CIE1976）利用不同的座标值给出了更均匀的色空间。
☆色差colourdifference
在规定色空间中，以2个试样色座标值之间的距离来确定两者颜色差异的客观量度。
☆色料索引号；染料索引号colourindixnumber（缩写CInumber）
由染料技师和色料技师协会出版的色料一览表中的色料参照代号，一览表中包括了对各种色料的叙述、类属名称和它们的成分。
☆颜色匹配colourmatch
如果在规定的照明和观察条件下，不能觉察色漆间的颜色有明显的差异时，则可认为它们的颜色相匹配。
☆色质colourquality
包括色调和饱和度，但不包括明度的颜色规格。
☆消色colourreduction
当某色料与冲淡色浆混合时，色料分散体的色调、亮度和饱和度的评定。这是一个与标准色料相对照的比较试验。
☆色彩浓度depthofshade
以色调和饱和度，但不以明度表示的色质。当所有其他条件（观察等）保持相同时，这种色质的增值与现有色料数量的增值有关。
☆主波长dominantwavelength
当与白光混合来匹配某涂层颜色时的纯光谱光的波长。对于黄色光而言，需要负量补色波长的绿光。
☆色调；色相hue
确定其是红、黄、绿、蓝、紫的颜色属性。
☆照明体illuminant
由某光源发射出的光或照射到表面上的光。其色质是由光谱能量分布确定的。
☆明度lightness
与色调和饱和度无关的表面反射光的比率。
☆主色；本色masstone
单一着色颜料在合适漆料中的分散体的颜色。
☆条件等色；条件配色metamericmatch
在同一照明体下而不在其他照明体下的色漆颜色匹配。该现象称为同色异谱，是由光谱反射率分布不同百引起的。
☆似远色recedingcolour
When a color is adjacent to its complementary color on the same plane, the human eye perceives it as farther away than its complementary color. Among such colors are blue and green.
☆Dilute color paste redutionpaste
Dispersion of white pigment in the same paint as the test color pigment. Among them, the paint can be air-drying alkyd, alkyd/amino baking system or thermosetting or thermoplastic acrylic resin, usually refined linen paint is used.
☆Dilution ratio reductionratio
The ratio of colored pigment to white pigment required to obtain a particular light shade.
☆Saturation
The degree of approximation of a color to the associated spectral color purity. Similar conceptual terms are chroma and color intensity.
☆Shade adjustment color shade
A color change resulting from the addition of black or white pigments.
☆ spectral match spectralmatch
Paint colors are matched at each wavelength of the visible spectrum, ie the reflectance of matching paints is the same. Spectral matching applies to all illuminants and observers.
☆standard depth of shade
A color density randomly selected for all hues, from which a uniform color density can be determined for comparison. Color density can be expressed as a multiple or percentage of standard color density.
☆Standard illuminant standardilluminant
A reference light that specifies the spectral energy distribution.
☆(rush) light color; light tint
The color formed by adding a small proportion of color paste or tinting paste to white paint.
☆Background color; thin layer color undertone
The color obtained when a pigment dispersion is used in a very thin film, or when diluted with a large amount of white pigment. The base color tone is often different from the main color tone.
☆Back stick (sex) after-tack
A paint film defect in which a painted surface has reached the tack-free dry stage and subsequently assumes a tacky state. This phenomenon is caused by the syneresis (i.e., the expulsion of liquid from the colloid) of underpolymerized oil or oxidation products.
☆Benardcells
During the drying process of the coating film, many hexagonal small cells are formed on the surface. Due to the color floating of the pigments, the edges of the celllets can take on a different color appearance. The mechanism of cell formation is attributed to the vortex action of the coating film due to the rapid evaporation of the solvent.
