Greenhow Blue vs J491
Where Greenhow Blue belongs to Benjamin Moore's range, J491 is a Tikkurila color. Greenhow Blue reads as blue-green, while J491 reads as blue — two distinct hue families, not close cousins. Greenhow Blue (LRV 55) reflects noticeably more light than J491 (LRV 52), a difference of 3 points that becomes especially apparent in rooms with limited natural light. The ΔE 5.9 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
