I recently switched to Thunderbird calendar and I really like it but I have just one question to make my calendar perfect.

When creatingan Event / Task Is there a way to isolate each Event / Task in their own box and fill color sollelction? When I go to print the calendar all that I see are the words. If I could color the boxes as I have done in the attachment (T-bird)from another calendar that I use to have, and the other attachment is printed from Thunderbird (T-bird-1)and it it would make it easier to see with bigger fonts and colored box.
