Preparation and Safety Guidelines

Tools Needed
  • 12x24 inch canvas (or larger)
  • Black gesso or black acrylic paint
  • Bob Ross Liquid Clear/Linseed Oil
  • Palette knife
  • Landscape brush
  • Flat brush
  • Soft fan brush
  • Cotton buds
  • Cocktail stick
  • Assortment of vibrant oil paints (e.g., bright orange, cadmium red, ultramarine blue, turquoise, titanium white, phthalo blue, yellow ochre, crimson)
  • Baby wipes (for corrections)
Safety Guidelines
  • Always work in a well-ventilated area. Acrylic paints and mediums can release fumes.
  • Protect your work surface with a drop cloth or plastic sheet. Acrylic paints are difficult to remove once dried.

  2. Layering Base Colors

    • Apply vibrant colors diagonally across the canvas. Begin with a base color (e.g., bright orange).
    • Blend in other colors, such as cadmium red and ultramarine blue, creating a textured effect using the corner of the brush.
    • Add more colors (turquoise, etc.), building layers and blending as you go to create a vivid, nebula-like effect.

  6. Optional Glazing

    • Apply a thin glaze of color (e.g., crimson) to add depth. If it looks muddy, remove and reapply a lighter glaze.

Tips

  • Use opaque colors for maximum vibrancy against the dark background.
  • Don't be afraid to experiment with color combinations; unexpected results often look stunning.
  • Keep brushstrokes random and energetic. The twirling motion adds a unique texture.
  • Use a light source to see how colors pop against the black canvas.
  • For a softer look, gently blend the edges of the colors with a fan brush.

Common Mistakes to Avoid

1. Overmixing Colors

Reason: Overmixing creates muddy, dull colors, losing the vibrancy of the nebula effect.
Solution: Blend colors gently, leaving some areas of distinct pigment for a more realistic nebula appearance.

2. Using Too Much Water

Reason: Excessive water dilutes the paint, resulting in weak colors and a lack of texture.
Solution: Use enough water to keep the paint flowing smoothly, but avoid creating a watery consistency.

FAQs

What type of paint is best for wet-on-wet nebula painting?
Watercolor or acrylic inks are ideal for wet-on-wet techniques due to their fluidity and ability to blend seamlessly. Acrylic inks offer more vibrancy and permanence, while watercolors provide a softer, more delicate effect.
How do I achieve that smooth, blended look in my nebula painting?
The key is to work quickly and wet-on-wet. Ensure your paper or canvas is thoroughly dampened before applying your colors. Use large, soft brushes to blend colors gently, allowing them to diffuse naturally into one another. Avoid harsh brushstrokes.
What if I make a mistake? Can I fix it in wet-on-wet painting?
While wet-on-wet painting encourages spontaneity, mistakes can be addressed. For watercolors, blotting with a clean, damp brush can lift excess color. For acrylic inks, you might need to work faster to correct mistakes before the paint dries, or potentially use a slightly damp brush to soften harsh lines.
