MAC Speak Louder is a slightly warm-toned, dark pink with a pearl finish. It is a permanent lipstick that retails for $19.00 and contains 0.1 oz.
MAC Speak Louder Cremesheen Lipstick ($14.50 for 0.10 oz.) is described as a "clean poppy blue pink." It's a vibrant medium-dark pink-red with a subtle blue undertone and a soft, natural sheen. MAC Impassioned is much more vibrant, more coral. MAC Party Parrot is much more coral. MAC Moxie is darker, more intense. MAC Full Fuchsia is more vibrant, brighter. Against my skin tone, it doesn't read as cool-toned as it is in the tube.
