If you really are using color themes (`color-theme.el')
then you have `color-theme-mode-hook', but that likely
won't help here.  There is no `color-theme-load-hook',
AFAIK.

On the other hand, if you are using custom themes then
there are `custom-new-theme-mode-hook' and
`custom-theme-choose-mode-hook'.

You have not yet made clear which kind of themes you are
using (though you keep saying "color theme"): custom
themes or color themes.
