Black blue vs Pale Green

Black blueRAL ClassicvsPale GreenRAL ClassicΔE 59.0Very different colors

Both are RAL Classic colors. Black blue reads as blue, while Pale Green reads as green — two distinct hue families, not close cousins. At LRV 31 vs 5, Pale Green will read as the brighter of the two — a 27-point gap that matters most in north-facing or low-light rooms. At ΔE 59.0, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

Front Door

Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. Pale Green returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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.
