The choice beside red brick and copper-colored metal
Red brick and copper-colored metal are specific warm neighbors; a heritage name cannot guarantee compatibility with their exact finishes.
Set up both candidates with red brick and copper-colored metal. Use equal-sized boards with the intended finishes and place them in the same orientation. Do not put one directly beside a window and leave the other in shadow. A difference that follows the position rather than the board is a lighting observation, not evidence that the formula changed.
What the comparison can—and cannot—settle
The alternative Cypress Green has an LRV of 35.09. The undertones and neighboring colors covers that related choice.
Test the actual brick and metal together before treating the historic name as a guaranteed period match. Assess Roycroft Bronze Green and Dark Olive alone as well as side by side. The unchosen board will not remain in the finished room, and a preference created only by that neighbor may not survive its removal. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
