No. Temari wears a black headband.

No, there was no romance between Naruto and Temari.
To be honest, I don't think there's anything special about the colour of them. For instance, Sakura has a red headband, Choji had a blue one as well (before Shippuden) and Temari has a black one. There are other colours as well, but I don't think it makes a difference.
Temari from Naruto has light green eyes.
Please wear a headband.

Each turtle has a unique coloured headband, so the audience can identify them when they are using their weapons.
A majority of the students in the Chunin Exam wore blue headbands but in Shippuden, some of them had changed the color of the cloth. (i.e. Black or Red.) Some characters such as Neji (black) still wears the smae color headband as they did during their debut. Others like Shikamaru and Yamato (Tenzo), wears it without the cloth.
There are some ninjas who do choose to wear a headband. However, this is a personal choice and it is not a requirement.
