Same color. Different material.
Satin chrome 626 is chromium plating on brass or bronze. The related 652 code specifies steel, while 630 is satin stainless steel. Use the code reference to check the material and process behind the appearance.
Black is a family, not one finish.
Flat black coated 622, black painted 693, black anodized 711 and a maker's BSP coating can differ in texture and sheen. Confirm the exact finish available on the selected hardware.
Keep the naming system attached.
A manufacturer's 716 can mean aged bronze. BHMA 716 identifies bright gold anodized aluminum. Include the manufacturer, complete model and finish name with the code on your order.
