Type of Colour:
- Additive = RGB COLOUR
- Subtractive = CMYK COLOUR
The RGB color model is an additive color model in which red, green, and blue light is added together in various ways to reproduce a broad array ofcolors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
The CMYK color model (process color, four color) is a subtractive color model, used in color printing, and is also used to describe the printing process itself. CMYK refers to the four inks used in some color printing: cyan, magenta, yellow, and key (black).
RGB VS CMYK
On-screen colour is RGB and print is CMYK. In effect, the two are opposites since again, one is subtractive colour and the other is additive colour. When you manipulate and create images in the digital environment, it’s all RGB—although programs like Adobe Photoshop allow you to convert to CMYK and effectively simulate the CMYK colour space on-screen.
