Oki OKIPAGE 8c Plus 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 Plus.
