Stained glass window panels that mirror your palette
If the three core colors in your palette are more than enough for you, play it safe by choosing some stained-glass window panels that match them. For the best results, consider focusing on hues that will contrast against their surroundings (in this case, your walls and window features).
A yellow design next to some yellow walls would end up being a bit too much. A blue panel mirroring the same hue that’s present elsewhere in the room but surrounded by white? Now we’re talking.
