About RAL 000 20 00
This is the shade you choose when black is too absolute. In interiors, a surface in 000 20 00 acts as a background that recedes without punching a hole in the room — you notice the difference from true black mainly in how the space feels, not in what you see.
Dark colours feel heavier than light ones, and that weight is determined almost entirely by lightness, not by colour. At this position the effect is at its strongest: a ceiling or overhead surface in this shade presses down on a room noticeably, while the same colour on a floor gives stability instead.
