Half white on the top and half black down. Looks like Hatsuharu Sohma from Fruits Basket o Horo Horo from Shaman King xD.

Saeki has blue deep eyes and, most important, a good sight.

This is Saeki when enters to the tennis court. Like a hunter after a big target.

He's tall in the scale of the japanese boys in Japan. Althougt, from all the Rokkaku boys, Saeki's the 3th shortest.
1. Bane (184 cm)
2. David (180 cm)
3. Shudou (176 cm)
4. Itsuki (174 cm)
4. Saeki (174 cm)
6. Ryou (168 cm)
7. Aoi (165 cm) 

With the height of all the characters, I still can't believe that nobody is older than 15 years old... 

The same design as many public schools and others. Seigaku & Fudoumine have the same type of uniform.

Because it's a manga picture, I'll describe colors.
-Shirt: Red with cream borders, with the school name in the left.
-Shorts: Plain white.
-Racket: Wooden. Made by Ojii.

This is a miniscene where Saeki is in a dance perfomance with Oshitari and Akazawa. Look the red jacket, black shirt and black hat. Simply gorgeous!

Child Saeki is so cute!!

This image is only from a poster, where they are all playing pool. I just liked this look. I just love ties *__*
