Как я могу упростить этот код, чтобы в нем не было так много операторов if if?

Я уверен, что это можно упростить, но я не совсем уверен, как. Любая помощь будет принята с благодарностью!

foreach($color_count as $k => $v) {
$index = count(json_decode($k, true));
if($v < $max_color_count[$index]) {
$diff = $max_color_count[$index] - $v;

if($k == '["White","Blue","Black","Red","Green"]') { $this->add($filteredCards['White-Blue-Black-Red-Green'], $diff); }

else if($k == '["White","Blue","Black","Red"]') { $this->add($filteredCards['White-Blue-Black-Red'], $diff); }
else if($k == '["White","Blue","Black","Green"]') { $this->add($filteredCards['White-Blue-Black-Green'], $diff); }
