Day 25 – Color Temperature

Day 25 – Color Temperature

Depth through Warm & Cool

Technique level: Intermediate
Duration: ~40 minutes

Paper:
Kreatima aquarelle 25% cotton (maybe).

Colors:
– Cobalt blue (Rembr.)
– Permanent Madder Brownish (Rembr.)
– Transparent Gold Deep (W&N)

– Payne’s Grey (W&N)

Objective:
Learn to use warm and cool versions of color to create spatial depth and emotional tone. You’ll paint a simple mountain range or a stylized portrait, shifting temperature across planes to push parts forward and let others fall back.

Materials:

  • Cold press or hot press paper
  • Transparent pigments in warm/cool pairs:
    • Warm: Quinacridone Gold, Burnt Sienna, Scarlet Lake
    • Cool: Ultramarine, Cobalt Blue, Phthalo Blue, Alizarin Crimson
  • Round brush (size 6-8) and detail brush
  • Optional: reference photo or memory sketch

Steps:

Option 1: Mountain Landscape

  1. Sketch three overlapping layers of mountains.
    • Closest = largest, furthest = smallest. No need for perfect realism.
  2. Layer 1 (Background/Furthest):
    Use a cool, diluted color – Cobalt Blue, or blue with a hint of cool red. Keep it soft and pale.
  3. Layer 2 (Middle distance):
    Slightly warmer and darker – try mixing blue with a touch of Burnt Sienna or Quin Rose.
  4. Layer 3 (Foreground):
    Richer, warmer tones – add more sienna, gold, or a deeper warm blue (Ultramarine) for close-up drama.
    Use more contrast here – this is where your eye lands.

Option 2: Portrait (Loose / Stylized)

  1. Sketch a head + shoulders or face silhouette.
    No need for realism – suggest the structure with a few lines.
  2. Block in skin and background with washes.
    Use warm tones (e.g., golds, pinks) for lit areas and cool tones (e.g., violet, blue) in shadowed sides.
    Think warm cheek, cool jawline; warm forehead, cool neck.
  3. Push with Glazes:
    Once dry, glaze in shadows with a cool tone (not just “darker,” but cooler).
    Let warm highlights pop by staying untouched or lightly glazed with yellow or rose.

Focus:

  • Warm = closer, lively, energized.
  • Cool = distant, calm, receding.
  • Use temperature contrast to suggest form, distance, and light direction.
  • This is color theory in action – not just “what looks pretty,” but what creates space.

Bonus Prompt:
Take the same mountain scene or portrait and reverse the temperatures. What happens when the background is warm and the foreground is cool? (Spoiler: it gets weird, but sometimes in a good way.)
