How to Rainbow Letter using Brush Pens:

First, look ahead and quickly count how many alphabets your word has My word “Rainbows” has 8 alphabets and I chose 8 colors of brush pens to use including a pink. So that means I’ll be lettering one letter in each color.

Step by step tutorial of Rainbow Lettering

Total Time: 10 minutes

Start your lettering with a Red marker

With the brush tip of your Red-colored marker letter the alphabet R

Letter the entire word

Changing the color for each alphabet letter your word.

Blend the colors with water

Using the paintbrush , squeeze a drop of water onto one letter at a time.
Slowly, use the water to blend the point where two colors meet. Go over the area with 2 or 3 brush strokes and stop. Don’t over blend.

Continue blending the rest of the alphabets

Let the water do the work for you and just softly blend the alphabets. Rainbow hand lettering tutorial

This is my favorite way of lettering- write the alphabets onto a mixed media paper first and then paint over each word with water to soften the colors and blend them slightly. ⁣

This creates a watercolor blended look that is so satisfying to paint!
