Use a night window to practise a large dark area, a small warm light, window-frame overlaps and reflected light on the wall.

One lit window can establish night without a whole street. Keep most areas quiet and warm light small. Use a blue wall, window and vague interior silhouette to practise light extent and obstruction, without an automatic glow filter.

## Reserve the bright window’s position first

Create a 1200×1600 portrait canvas with dark blue-gray. Sketch a window about 420×650 upper-right, about 300 below the top. A slight handmade tilt is fine if sides agree. Leave broad dark wall left and room below for sill and wall shadow.

Prepare dark blue-gray, lighter cool gray, dark brown, warm orange and pale yellow. Reserve the lightest until the focus is clear. Separate wall, light and frame so repairs do not erase illumination. Few layers suffice; see [Three-layer workflow](<https://allluckly.cn/en/guides/aquarell-three-layer-workflow/>)for organisation.

## Establish night with an uneven dark wall

Add a little cool gray over the base with a 180–250 pixel brush at 20% to 35%. Keep wall changes gradual, not striped. Slightly lighten near the window and darken edges to guide attention. This is manual layering, not dependent on gradients or blend modes.

Limit wall texture to a few places, such as two or three sill marks and one old-wall patch. Keep contrast below that between light and frame. Lower the texture layer if distracting. Night painting deliberately reduces visible content rather than merely turning daytime objects blue.

## Divide warm window light into three levels

Fill the light layer with medium warm orange. Add pale yellow near the indoor light over about one-quarter of the window, retaining orange or brown-orange elsewhere. Brightest light may be high or to one side, not everywhere, suggesting interior space rather than a glowing sticker.

Paint a dark-brown interior silhouette, such as a plant or partial curtain. Use simple shapes: a flat trapezoid pot, three or four leaf strokes, or one curved vertical curtain edge. Obstruct some light without furnishing the whole room. Slight warmth relative to the darkest exterior suggests indoor space.

## The frame divides the light

On the frame layer, use a 20–35 pixel dark blue-brown brush for side frames, top and one crossbar. Place the crossbar around one-third of the window height rather than mechanically centred. Keep widths broadly consistent, adding a narrow warm-gray lit edge to suggest thickness.

Extend the sill about 40 pixels each side and add a thin dark shadow beneath. Bright edges belong mainly towards the light, not equally around the window. Repair misplaced framing with a small eraser on its layer instead of repainting light. For edges, see [Hard- and soft-edge exercise](<https://allluckly.cn/en/guides/aquarell-edge-study-stones/>)for explanation.

## Carry a little light onto the wall

Between window and wall, add a layer with warm gray far darker than the window. Lightly brush once or twice near the sill using broad low-opacity marks. Extend glow about 40 to 90 pixels beyond the frame, unevenly, perhaps stronger below the sill and fading quickly away.

Light on the wall takes on wall colour, not the same vivid yellow as inside. If fluorescent-looking, reduce saturation and area. Reserve palest yellow for a small interior area and short frame reflection. Differentiated bright marks concentrate the warm light.

## Compare obstructed and unobstructed light

Leave a narrow light gap beside the interior silhouette and a broader lit area opposite. Asymmetry shows obstruction rather than uniform glow. Hide the silhouette: if the window flattens, it helps; if little changes, adjust its size, position or value. Keep one readable dark form rather than immediately adding furniture.

## Judge atmosphere from the thumbnail

Hide the sketch and view the whole portrait. Notice the window first, frame and silhouette second, wall variations last. If the left wall feels too empty, add one faint horizontal seam before considering another equally bright window. Empty space contributes to night’s quietness.

**Why does it look like a yellow daytime window?** Usually the wall is too bright, the window too large or background detail too distinct. Increase wall–window value separation and reduce background detail; not every dark area needs pure black.

**Must a soft brush be used for glow?** No. Two or three related warm grays in progressively smaller areas make a hand-painted transition. A soft brush is another control method, not an automatic light-direction fix. Equal glow widths without sill reflection still look unnatural.

Keep frame and light separate in the saved original. For the next exercise, make the same window cold dawn light by changing relative wall/window values and colours, comparing atmosphere instead of adding objects.
