What does this Zig snippet output?

1const std = @import("std");
2const Color = enum(u8) { red = 1, green = 2, blue = 4 };
3pub fn main() void {
4    const values = [_]u8{ @intFromEnum(Color.red), @intFromEnum(Color.green), @intFromEnum(Color.blue) };
5    var sum: u8 = 0;
6    for (values) |v| sum += v;
7    std.debug.print("{d}\n", .{sum});
8}
