The starter vertex stage transforms positions and passes vertex colors.

#version 330 core
layout(location = 0) in vec3 a_position;
layout(location = 1) in vec3 a_color;
uniform mat4 u_model;
out vec3 v_color;
void main() {
    gl_Position = u_model * vec4(a_position, 1.0);
    v_color = a_color;
}
