RGB

RGB stands for Red, Green, and Blue — the colour model used by screens, monitors, televisions, and all digital displays. In the RGB model, colours are created by combining light in three channels. Each channel has a value from 0 to 255, giving over 16 million possible colour combinations. RGB is an additive colour model: adding more light produces lighter, brighter colours, and combining all three channels at full intensity produces white. This is the opposite of CMYK, which is a subtractive model where adding more ink absorbs more light and produces darker colours. For logo design, RGB values are the correct specification for any digital application — websites, apps, social media, email, and screen-based presentations. Colours that look vibrant in RGB may appear slightly different when converted to CMYK for print, particularly highly saturated blues and greens. Brand guidelines should provide both RGB and CMYK values for each brand colour to ensure consistency across media.
