====== Direct classification on Color-codes ======

A direct color classification is a special use case of [[2210:desktop:dataset:legend:classification:direct|direct classification]]. This direct color method is frequently used by [[2210:technology:supported_formats:vector:fme|FME resources]].

===== Hexadecimal Color-codes =====

The structure of Hexadecimal Color-codes:

**Always begin with FF:**
\\  
<code>For example : Black: FF 00 00 00, Pink FF C0 CB</code> \\
The first 2 zero sings are for R(ed), the 3th en 4the for Y(ellow) and the 5th and 6th zero are for B(lue) \\ \\
**To calculate the decimal code to use in Orbit GIS you need to use a scientific calculator** \\ \\

==== Example : White ====

The Color "White" is FF FF FF FF in the Hexadecimal RGB-code. In Orbit Gis (Graphic Attributes)  white has the decimal code -1 \\ \\

  * Change the screen of the calculator onto ''scientific'' and choose decimal.
  * Calculate 2 to the power 32 (use the button x ^ y). Save your result with the M + button.
  * First choose hexadecimal on the calculator and then enter the color code.
  * Choose again the decimal mode and reduce the number with 2 to the 32th power (use the stored number by using the MR button) 
  * The result is the code that can be entered in Orbit GIS.
