Hi Suleman,
I was also unable to set offset and midpoint of color scale using tcl
commands in the tk console without changing one another, as you described.
Those variables are likely to be bound in src code.

Before diving into source code to investigate the issue, would you
share what you would like to achieve?
It might be more straightforward to redefine a color method.
