I used Illustrator for a large format design when printed a proof in glossy paper the colors were not bright at all I used CMYK How can I get very bright colors?
ensure that you use the cmyk option from the start of your design, and that illustrator does not default to rgb. Try printing in rgb if the colors brighten up there is a good possibility you created the large format design in rgb. rgb for webstuff and cmky for printstuff from the very beginning!
Which colour has the largest color gamut-rgb or cmyk?

Rgb cmyk hsl or pantone in a document?
If you're printing the image on your desktop printer, use RGB--those printers will convert anything else to RGB, then to CMYK. If you're printing it on a wide-format inkjet printer like a Roland, Mutoh or VUtek, or you're sending it to a printing plant to be printed on an offset or flexo press, use CMYK if you're not using spot colors, and Pantone for the spot colors.
What image modes have color gamuts larger than that of CMYK?
RGB is usually the best and has the widest variety of colors
How is RGB and CMYK related?
RGB is color mode which is suitable for screen, CMYK for printing with process colors. In most cases to print image you will first work with it in RGB color mode because you are watching your work on screen then you will need to convert to CMYK. RGB model is created from 3 main colors Red, Green and Blue, CMYK color mode is created from 3 opposite colors to Red, Green and Blue and they are Cyan, Magenta and Yellow plus Black color Ink. You can manage colors in RGB mode by increasing or decreasing participation of Cyan, Magenta or Yellow which are opposite colors on color wheel. In Curves dialog you can increase participation of Red color for example but also decrease by increasing participation of Cyan (pull curve in opposite side).
Are chameleons RGB or CMYK?
neither
Why should you use CMYK when working with information that will be printed?
Screens reproduce colors by mixing blue, green and red lights (RGB). Printers reproduce colors by mixing cyan, mangenta, yellow and black inks (CMYK).
Offset printing cmyk or rgb which is best?
CMYK is the only color mode you should be using for typical offset printing. Those are the primary colors for printing and therefore are the colors in a press. RGB are the primary colors in video monitors--totally different world. There are other forms of offset printing including hexachrome and hi-fi, but that's irrelevant to what you're asking.
Why does cmyk make the colors go dull?
well, let me try to explain the answer i am sure that you will reach to the answer... RGB and CMYK are different colour system. RGB Stands accordingly as Red, Green and Blue and CMYK stands accordingly as Cyan, Meganta, Yellow and Black. * RBG colour system is based on "The colour of light Rays" and * CMYK colour system is based on "The Reflection of light Rays" The Reflection of light is always dull than actual light so CMYK make the colors go dull.... - mayur_vaghela@yahoo.co.uk
What happens when you convert RGB to CMYK?
The underlying color model in Photoshop is neither RGB nor CMYK but LAB. It has the widest gamut, which means it can hold more color values than any other model. Of the two other models, RGB has more color values than CMYK does. When you convert from RGB to CMYK, the program first "maps" the RGB values into the LAB colorspace. It then maps the LAB values into the CMYK colorspace. Now, for REAL entertainment...take a pure RGB blue, or a pure RGB green, and attempt to map it into CMYK colorspace. It doesn't work at all. Red maps fine, but the other two go straight to hell.
What happens if a printer uses RGB cartridges instead of CMYK?
go buy RGB cartridges
