About 90% of detections are under 20 MW, so the old blue and teal stops painted most of the map in cold colors that do not read as fire. The ramp now runs ember, red, flame, orange, gold and white-hot at the same thresholds, each stop lighter than the one below, so the brightest marks are the strongest fires. The heatmap uses the same colors.
