Bright Blue CMYK is (90, 70, 0, 0); meaning it has 90 of cyan, 70 of magenta and 0 of both yellow and black. This translates to an approximate hex code #2A5CAB and RGB values of (42, 92, 171). The CMYK system is the foundation of color printing technology that runs both large industrial and small desktop printers. Colors are created using only four inks - cyan (C), magenta (M), yellow (Y) and black (K). Please understand that bright blue CMYK as it looks on the screen may not be reproduced exactly on printed paper not only because of the two different color models - hex and CMYK - but also because of the quality of the printer, the paper and the four inks.
NOTE: The bright blue (CMYK) hex color code mentioned on this page is just an approximation. It has been calculated from the CMYK values. As you probably know, the CMYK color model is for print media while hex codes and the equivalent RGB values are for screen. The two can seldom be converted correctly. Additionally, bright blue color displayed on the screen through its hex code, may look very different when printed (by the CMYK values).
