I have posted about these triangular lamps a few times already but will try to share new colors as I find them. The others I have found so far are in black, yellow, and most recently just last week, blue (and yellow). The lamps are approximately 10” tall by 7” wide. They all have an acrylic shade that looks like a sphere embedded in the lamp when viewed from the side. Here is the lamp in avocado green.
