In the RGB color mode, various colors can be obtained by mixing three primary colors, such primary colors are R (red), G (green), and B (blue). If the mixing ratio of these three colors is the same, it can be superimposed to produce white light. This color mode uses the "addition principle", that is, the mixing of colour light, where two or more colours can be mixed to produce a different colour light, and the brightness of the light is increased, the total brightness of the mixed colour light is the sum of the brightness of all the colours mixed together. Simply put, the more you mix, the brighter the color will be.
CMYK Color
CMYK is a colour mode that applies the 'subtractive principle'. Subtractive mixing is mainly the mixing of pigments, when we need to print different colours, we need to mix two or more pigments to produce a new colour. The various colours we see in the pigments are due to the absorption of certain colours of light by the different pigments and we observe the remaining light. Simply put, the more you mix, the darker the color will be. In general, CMYK colours are more suitable for printing than RGB, but there is still a large difference between the CMYK colour displayed on screen and the actual colour, so neither is suitable for colour matching reference, while the other PMS colour is widely used for colour matching reference.
PMS Color
The Pantone Color System, or PMS, is a standardized color matching system, which is widely used around the world. Pantone transfer the inks color it produced into color cards, and numbers them according to the rules of pantone001, 002, 003... The color numbers we come into contact with are generally composed of numbers and letters, such as: 105C pantone, which represents the effect of printing the color of pantone105 on glossy coated paper. Print the pantone color number on different materials to form different color cards. The function is to clarify the value of the printed color and provide reference for designers in different industries. C=glossy coated paper U=matte paper TPX=textile fabrics TC=cotton fabrics For color matching, you only need to know the color number and color card type of the other party.
