It seems like you are calling the size function count() as part of the test condition. You might want to compute the size beforehand, and not on each iteration.

					$colors_build[] = $colors_base[$i];

					if($i < count($colors_base)-1) {
						$colors_build[] = holt45::colorBlend($colors_base[$i], $colors_base[$i+1]);
