Oki OKIPAGE 8c Colour Manual page 13

Each of the models have their benefits and disadvantages
and are useful in particular situations. Most applications will
have support for the RGB model which (along with CMYK)
is perhaps the simplest to use. This model is used to specify
colours by varying the proportions and levels of the red, green
and blue components.
The amount of red, green and blue present in a colour is usually
expressed as a number from 0 to 255. Less commonly it may
also be expressed as number between 0 and 65535 or as a
percentage. Converting between the systems is straight
forward and a few examples are given below:
Example: To achieve a colour that is described as 100% red,
50% Green and 40% blue...
255 Colour scale: 100/100 ×
50/100 ×
40/100 ×
65535 Colour scale: 100/100 × 65535
50/100 × 65535
40/100 × 65535
Colour Guide
255 = 255 red
255 = 128 green
255 = 102 blue
= 65535 red
= 32768 green
= 26214 blue
The printout from this set of numbers should produce a
colour close to the original. Due to the variation in printer
inks however, it may be necessary to make minor adjustments
until the right combination is found. Once a colour match is
obtained, the RGB components should be entered regardless
of the colours displayed on-screen. To maintain colour
consistency it is recommended that OKI original consumables
are used as they are specifically manufactured for the
OKIPAGE 8c.
