SYMPTOMS
If you try to use Visual Basic for Applications to specify the process color values of an object, the color values are not rendered correctly on screen.

For example, the following line of code ActiveDocument.Pages(1).Shapes(1).Fill.ForeColor.CMYK.SetCMYK 0, 0, 100, 0 creates a pale yellow with the RGB values of Red: 255, Green: 249, and Blue: 169. The CMYK values are Cyan: 0, Magenta: 0, Yellow: 39, and Black: 0.



CAUSE
This behavior can occur because Publisher uses one set of ranges in the More Colors dialog box for color settings for process CMYK colors, and a different range in Visual Basic for Applications and internally to the program for the color model.

In the More Colors dialog box, process CMYK colors range from a value of 0% to 100%.

Although the More Colors dialog box uses the range of 0 to 100 for process CMYK colors, Publisher stores process CMYK colors in memory as a range from 0 to 255. Visual Basic for Applications uses the 0 to 255 values to access the colors rather than using the 0 to 100 range.

The following sample code is just one way to convert CMYK values of 0 to 100 to 0 to 255. It is a function that passes the 0 to 100 values and the shape to be colored. The code does not return any value; it just changes the colol of the object on the page. Function MakeCMYK(lC As Long, lM As Long, lY As Long, lK As Long, _   oShape As Shape) '  ' The shape is passed into the function so that ' it may be operated on directly. '  ' The function is passed the values of 0 through 100 then ' it multiplies each by 2.55 to convert it to a range of  ' 0 to 255. '  lC = lC * 2.55 lM = lM * 2.55 lY = lY * 2.55 lK = lK * 2.55 '  ' Set the shape's forecolor fill to the correct CMYK ' values. '  oShape.Fill.ForeColor.CMYK.SetCMYK lC, lM, lY, lK End Function
