Marabu Rainbow Alcohol Ink

Marabu Rainbow Alcohol Ink is not a standalone color — it’s a special effect additive that transforms your inks with a subtle rainbow shimmer.

When added to alcohol inks, this creates a color-shifting effect that catches light and shifts tones depending on movement and angle. Instead of changing the base color, it enhances it with a soft iridescent glow.

This is how you get that “oil slick / rainbow sheen” look without using glitter.

Alcohol inks themselves are:

• transparent
• fast-drying
• highly blendable
• ideal for fluid effects and organic movement

This additive takes those effects and pushes them into a more dimensional, high-end finish.

Where this shines

• alcohol ink paintings
• resin surface effects (top layer only)
• geode accents (light shimmer lines)
• mixed media work
• fluid abstract art
• enhancing metallic or pearl inks
• adding movement without sparkle

Product Details

Type: Alcohol Ink Additive
Effect: Rainbow / Iridescent shift
Finish: Sheer shimmer (not glitter)
Base: Transparent

Use:
• mix with alcohol inks
• drop into wet ink for bloom effects

Important:
Alcohol inks are transparent and dye-based, meaning:

• they create flow and movement, not solid coverage
• they can fade over time without protection
• adding liquid to resin can affect cure if overused

FAQ

Is this a color or an effect?
This is an effect additive — it adds shimmer, not color.

Will this work in resin like pigment paste?
Not the same. It’s best used on the surface or in small amounts.

Does this replace metallic pigments?
No — it’s much more subtle and transparent.

Can I use this alone?
You can, but it’s designed to enhance other colors.

What does it actually look like in use?
Think soft rainbow sheen — like oil on water.

Quick reality check (so you don’t get burned)

Here’s where people mess this up:

• they expect opacity → you won’t get it
• they pour it heavy into resin → cure issues
• they use it on dark bases → effect disappears

Flip that into smart use:

• use it lightly and intentionally
• use it over light or reflective surfaces
• treat it as a finishing effect, not a base color
