The information in this article applies to:
 
 - Microsoft PowerPoint for Macintosh, versions 3.0, 3.0b, 4.0
 - Microsoft PowerPoint for Windows, versions 3.0, 4.0, 4.0a, 4.0c
 - Microsoft Graph for Windows, versions 3.0, 5.0

SUMMARY
=======
 
When you match a color from a third-party program to a color in PowerPoint,
you may need to convert the color's values to the equivalent PowerPoint
color values. This article includes conversion tables to convert between
PowerPoint RGB, Standard RGB, and Apple RGB.
 
MORE INFORMATION
================
 
RGB stands for red, green, and blue. You can specify a color by giving a
value for each of these three components.
 
PowerPoint uses a scale where the R, G, and B values are all numbers
between 0 and 65535 inclusive (48-bit color). Many other programs,
including Microsoft Graph for Windows, use a scale where the R, G and B
values are all numbers between 0 and 255 inclusive (24-bit color). Apple
has yet another scale where the R, G, and B values are all numbers between
1 and 100 inclusive (24-bit percentage color).
 
You can convert between one scale and another by applying common
mathematical operation to each of the R, G, and B components.
 
PowerPoint (48-bit) RGB to Standard (24-bit) RGB
------------------------------------------------
 
Divide the PowerPoint RGB values by 256 to get the corresponding Standard
RGB values. For example:
 
   PowerPoint RGB             Standard RGB
   ---------------------------------------
 
      R:  4608      /256 =       R:  18
      G:  5120      /256 =       G:  20
      B: 64768      /256 =       B: 253
 
Standard (24-bit) RGB to PowerPoint (48-bit) RGB
------------------------------------------------
 
Multiply the Standard RGB values by 256 to produce the corresponding
PowerPoint values. For example:
 
   Standard RGB              PowerPoint RGB
   ----------------------------------------
 
      R:  18      *256 =       R:  4608
      G:  20      *256 =       G:  5120
      B: 253      *256 =       B: 64768
 
Apple (Percentage) RGB to Standard (24-bit) RGB
-----------------------------------------------
 
Multiply the percentage by 256 then divide the total by 100. For example:
 
   Apple RGB                       Standard
   ----------------------------------------
 
     R: 38  * 256 =  9728   /100 =   R: 97
     G: 56  * 256 = 14336   /100 =   G:143
     B: 34  * 256 =  8704   /100 =   B: 87
 
Standard (24-bit) RGB to Apple (Percentage) RGB
-----------------------------------------------
 
Multiply the RGB value by 100 then divide by 256. For example:
 
   Standard RGB                     Apple RGB
   ----------------------------------------
 
     R:  53  * 100 =  5300   /256 =   R:21
     G: 103  * 100 = 10300   /256 =   G:40
     B:  67  * 100 =  6700   /256 =   B:26
 
Apple (Percentage) RGB to PowerPoint (48-bit) RGB
-------------------------------------------------
 
Multiply the percentage by 65536 then divide the total by 100. For example:
 
   Apple RGB                             PowerPoint
   ------------------------------------------------
 
        R: 38  * 65536 = 2490368   /100 =   R:24904
        G: 56  * 65536 = 3670016   /100 =   G:36700
        B: 34  * 65536 = 2228224   /100 =   B:22282
 
PowerPoint (48-bit) RGB to Apple (Percentage) RGB
-------------------------------------------------
 
Multiply the RGB value by 100 then divide by 65536. For example:
 
   PowerPoint  RGB                     Apple RGB
   ------------------------------------------------
 
        R: 24904  * 100 = 2490400   /65536 =   R:38
        G: 36700  * 100 = 3670000   /65536 =   G:56
        B: 22282  * 100 = 2228200   /65536 =   B:34
