atom red,green,blue,skin
red = 255
green = 200
blue = 100
skin = create(wxColour,{red,green,blue})
Later I change skin with color_selector().
That works but there seems to be no way to save the color to a file.
Saving skin to file does not produce a consistent result.
That is, set_back_color(Win, skin) works,
but when skin is saved to a file, and then the program is stopped and restarted
and it reads skin,
set_back_color(Win, skin) doesn't work.
Unless there is a bug in the way I'm doing it.
Also there seems to be no way to derive red,green,blue from skin. That would be
ideal. Then the ini file could be edited.
How can a color from color_selector() be saved to a file?

I don't use wxEuphoria but I do use XColors in Xmotor,
I think you'll find that skin is a pointer the structure
that contains your color.
So when the program ends that pointer is no longer valid.
You will probably have to save the three color values in an ini file.
Then when your program starts do a
skin = create(wxColour,{red,green,blue})

The question boils down to:
how to get the 3 colors from color_selector()?

Instead of trying to get the value from the color selector, why not try
grabbing the values of the colors since they're easier to work with?
Something like printf might work for what you're trying to do.
printf ( FILE, "%d,%d,%d", {Red,Green,Blue})
Hope that helps.

How do I get red,green,blue?
I know how to do everything else.

You can use these functions to get the color components:
--/topic wxColour
--/func get_red( atom color )
--
--Returns the red intensity of a wxColour.
global function get_red( atom color )
return and_bits(call_member( wxColour_Red, color, {} ), #FF)
end function
--/topic wxColour
--/func get_green( atom color )
--
--Returns the green intensity of a wxColour.
global function get_green( atom color )
return and_bits(call_member( wxColour_Green, color, {} ), #FF)
end function
--/topic wxColour
--/func get_blue( atom color )
--
--Returns the blue intensity of a wxColour.
global function get_blue( atom color )
return and_bits(call_member( wxColour_Blue, color, {} ), #FF)
end function

Thanks. It works.
