How Can I Mix Different Colours of Paint Without Them Blending Together?

Click For Summary
SUMMARY

The discussion focuses on techniques for mixing multiple colors of paint without them blending into new colors, specifically for liquid art. The primary method suggested involves using a viscous base, such as methylcellulose, to maintain color separation. Participants recommend pouring colors into the container quickly to prevent diffusion and suggest using oil and water to create distinct layers. The conversation also hints at the potential for exploring non-mixing liquids to achieve clearer color separation.

PREREQUISITES
  • Understanding of liquid art techniques
  • Familiarity with methylcellulose as a paint medium
  • Knowledge of color theory and paint properties
  • Basic principles of viscosity and diffusion
NEXT STEPS
  • Research the properties of methylcellulose in art applications
  • Explore techniques for layering oil and water-based paints
  • Investigate non-mixing liquids suitable for artistic applications
  • Learn about viscosity modifiers and their effects on paint behavior
USEFUL FOR

This discussion is beneficial for artists, particularly those involved in liquid art, as well as paint manufacturers and chemical engineers interested in color separation techniques.

I am looking for a way that I can mix many colours of paint into the same container without it blending together and making other colours. I make liquid art and have seen others make images where i can see many colours in the liquid. The base of what I use at the moment is methycelluslose , water and acrylic paint. Image below to give an idea of what i do

Since the coloring agents are generally of the same specific gravity and share a common base, there is little to keep diffusion from eventually mixing the colors.
The most obvious way to counter this is to use a viscous base and use the paint before diffusion has a chance to mix. Since the base is often viscous anyway, simply pouring one color into the same container as the others should give you separated colors that will remain separated plenty long enough to work with.

But the photo you show looks like a water-based fluid. For non-viscous liquids, try dying oil with one color and water with a second color. The colors will still bleed, but for a while, they will stay in their own layer.

Ideally, you might be able to find liquids that don't mix and keep their color without bleeding. Perhaps one of the chemical engineers can help with that.

What exactly are you trying to do?
