<div class="desc"><p>Multiplies every framebuffer pixel by <code>color</code> (a <code>0x00RRGGBB</code> tint), channel by channel (<code>channel * tint / 255</code>). This is the global modulate that sets mood before any light adds brightness back: a dim blue-grey gives night, a warm brown gives a cave, and <code>0xFFFFFF</code> is a no-op. Call it once, after drawing the scene and before the <a href="light-point"><code>Light.point</code></a> calls that light it back up.</p></div>
