Version :

The color class functions apply records to the InDesign® color panel. The color can be defined using RGB, CMYK and LAB. If a color record already exists in the panel, the record remains unchanged.

The following scwatches are defined always and be addressed by their internal names. Pleae note, that you cannot change the base colors!

static int define_rgb(
  char* cname,
  int r,
  int g,

  int type = 1,
  ItemRef createdEntry = 0)

Define a new color entry in the InDesign® color panel. If there is already an entry with this name in the panel, the request has no effect - the pre-existing color will not be changed.

Name Type Default Description
Return int   0 or ErrorCode
cname String or char* - Name, under which the color should be applied. If the name is empty, no entry is created in the color panel. To change existing swatches, please use redefine_swatch.
r int - Red proportion of the color 0-255
g int - Green proportion of the color 0-255
b int - Blue proportion of the color 0-255
type int 1 Color type
0 Spot
1 Process
createdEntry ItemRef 0 On return it contains a reference to the used color entry. You must allocate this variable using item::alloc before!

Create the color entry 'Red'¥ err_code = color::define_rgb ("Red", 255, 0, 0);

The color type can be defined from version 1.0.20 on. Previous versions define colors always as process colors.

Please note : InDesign Server® cannot perform the function anymore since version 2021. The error is in InDesign Server itself - we as plug-in developers have no way to work around this problem. This is what the Adobe Support said: "Only awkward way available would be to delete using desktop application. I wouldn't call it a workaround though. So, as of now, there is no workaround. Thank you.

Unfortunately, we cannot say when the problem will be solved. The last we heard on the subject from the Adobe Support was "Yes, this problem is a known issue and has already been reported by few other partners as well. We are pushing to get this bug fixed within next release. I'll keep you informed as soon as fix is available."  That was on Nov 28, 2022. Anyway, today the problem still exists in InDesign Server 2023.
