Luogu Name Color Determination

The color of a Luogu user's name is directly linked to the scores of their five G-value indicators. Given the five scores, determine the user's name color using the formula:

Let \(S = s_1+s_2+s_3+s_4+s_5\). Then:

• If \(S < 600\), the name color is Green.
• If \(600 \le S < 1000\), the name color is Blue.
• If \(S \ge 1000\), the name color is Red.

It is guaranteed that the input user is neither a brown-named nor a purple-named user.

Refer to the Luogu G-value System Introduction for more details.
