Colors and mail: how to handle read mail?

Hi.

I have just enabled the colors in my inbox in roder to differ sender’s by categories: it works fine.

But, when I read it the color is still teh same I have choiced, instead of becoming the natural black.

I’m missing something or Lotus/Iris should consider to add a preference also for default colors so that I can change the red and black default to something else and, most important of all, I can choice to have all my emails to be submitted to my read policy ?

Thanx in advance for any answer.

Regards,

Simone
