Cyan,Magenta,Yellow, Key(black) are process colorsused for 4-color printing. Euroscale is an european standardizedchart based on this system.Offsetprinting uses fourprinting plates, corresponding to each one of the process colors. But also digital printers, ink jet or laser, work with this system.
Internationalcolor system consisting ofmore than 1,000solid colorsandmixtures.These are mainly divided intoPantoneCoated (for coated paper),Uncoated(coated paper)and solid-to-process(pantone to CMYK,Euroscale).
RGBis an additivecolor space, which is producedbymixing threeprimarycolors(red,greenand blue).RGBis a color space only suitable for the reproduction of color in self-luminoussystems (displays,monitors, videoprojectors, camera, etc.).RGBis not suitablefor printing!
TheWeb-safecolor palette was developed in a time whenmostcomputers couldonly display256 differentcolors (8bit).TheWeb-safecolorsareindicatedin hexadecimal values of RGB.Thistwo digitsdenotethe intensity ofeachof the three colorchannels red, green andblue inthat order.So for example#FF0000 is Red, #00FF00Green and #0000FFBlue.Due to theprolifeartionof video cards andmonitors thatcan displaya color depth of 24-bitorgreater, this limited range ofweb-safecolors has actuallybecomemeaningless, being however still widely used.
Palette ofpredefinedcolors.Usedmainly forsurface and wall paint.OriginallyRAL (Committeefordelivery conditions) served thestandardizationof color use in thepublic domain(eg,3000 Fire Red for fire engines).Use: Outdoor advertising,laminates, machines, furniture etc.
Good to know!
The reproductionof a color with other colorschemesor chartsisonlyremotely possible.This is due tothe differenttypes of colorcompositionand the different rangeof each chart.An exactmatch of acolorshadebetweentwosystemsis very rare.
