There's no direct support for writeable colours in GdkRGB.

Allocate - yes, but not to change the value of previously allocated 
writeable colour.
I need to have a constant pixel value (initialized by 
gdk_colormap_alloc_colors
in startup time) and ability to change the R/G/B values of this pixel. I 
can't find
non-deprecated functions to do this - that's the main reason of my screams.

Nope.
