The eight shades we supply split roughly into four darks — Charcoal, Coffee Brown, Jet Black and Slate Grey — and four lights — White, Golden Sand, Caramel and Terracotta. Choosing between the two halves is a bigger decision than choosing within them, and it turns on things that are easy to overlook standing in a shop holding a sample.
Heat
A dark surface absorbs more solar radiation than a light one and runs hotter. On a west-facing wall through an Indian summer that is a real difference, not a theoretical one, and it matters in two ways: the comfort of the rooms behind, and the amount of thermal movement the wall goes through every day.
This is the strongest argument for light shades on large, sun-exposed elevations, particularly in hot, dry regions. It is also why dark shades are often best used as an accent — a band, a panel, a column line — rather than across a whole south or west face.
Dust and dirt
This one surprises people, because it runs opposite to the assumption. In most Indian conditions the dominant soiling is dust, which is pale. Pale dust shows more on a dark wall, not less. A charcoal elevation on a dusty road looks dull sooner than a sand-coloured one on the same road.
Where the soiling is dark — heavy traffic pollution, soot, or a shaded damp wall growing algae — the reverse applies and dark shades hold their appearance longer.
Either way it is soiling rather than degradation, and it washes off. But it decides how often you will want to wash.
Rain marking
Water running off a sill, a ledge or a leaking gutter leaves streaks, and streaking is more visible on dark surfaces. If your elevation has many horizontal projections and the drip details are not good, a lighter shade will be more forgiving. Better still, fix the drip details — see wall seepage.
Fading
Marble texture carries its colour largely in the stone rather than in a pigmented film, which is one of its real advantages over paint. Even so, any exterior surface changes over years of direct sun, and a change is generally more noticeable on a dark shade than a light one — and most noticeable of all where one part of a wall is shaded and another is not.
Scale of the building
Dark shades visually reduce a building; light shades expand it. A large elevation entirely in Charcoal or Jet Black can read as heavy, especially on a narrow street where you cannot step back from it. A small house or a boundary wall carries a dark shade comfortably.
The arrangement that works most reliably on a full elevation: a light field with dark accents — Golden Sand or Caramel across the face, Charcoal or Slate Grey on the plinth band, column line or entrance surround. It handles the heat, the dust and the scale all at once.
Grain changes how a shade reads
Worth knowing before you judge a sample. Coarse grain casts deeper shadows between granules, which makes any shade read darker on the wall than it does on a small board. A mid shade in coarse grain can finish noticeably darker than expected. Look at samples in the grain you are actually buying — grain sizes.
A practical way to decide
- Which face takes the afternoon sun? That face argues for lighter.
- What colour is the dirt where you live — pale dust or dark pollution?
- How close does the viewer stand? Close viewing favours lighter on large walls.
- What is next to it — the neighbouring buildings, the boundary wall, the grille and gate colour?
- Then get samples of your two finalists, in the correct grain, and look at them on the actual wall at morning, midday and evening. This step changes minds more often than any of the others.
