How to Mix Greys and Do Line & Wash with a Fountain Pen

Kevin Thiemann |

Fountain pen enthusiasts and watercolor hobbyists rejoice! Have you ever wondered how to elevate your urban sketches or monochrome studies with beautifully dynamic grays? Mixing your own unique gray tones, combined with the versatility of a fountain pen, can bring unmatched depth and character to your artwork. This article explores the nuances of creating your own grays using watercolors, the benefits of avoiding pre-mixed grays, and how to incorporate these techniques into your sketches. Whether you're a beginner or seasoned artist, this guide will inspire you to approach your art with playfulness and creativity.

Let’s dive into the fascinating world of grays and how they transform sketches into captivating visual narratives.

Why Mix Your Own Grays?

One of the main takeaways from the video is the power of creating your own grays instead of relying on pre-mixed options like Payne’s Gray or Ivory Black. Pre-mixed grays can often feel flat, lifeless, and overwhelming, overshadowing other colors in your palette. As the creator points out, "Black is just a powerful animal that can trample over everything else." Instead, mixing complementary colors introduces subtle variations, texture, and personality into your work, giving your grays a unique vibrancy.

The Color Theory Behind Mixing Grays

To craft your own grays, an understanding of complementary colors is essential. Complementary colors sit opposite each other on the color wheel (e.g., blue and orange, red and green). When mixed, they create neutral tones, often resulting in shades of gray. The beauty of this approach lies in the ability to control the warmth or coolness of the gray based on the proportions of each color.

Here’s a quick summary of complementary pairs:

  • Blue and Orange
  • Red and Green
  • Yellow and Purple

By experimenting with the ratios of these color pairs, you can create an endless array of grays, from warm, earthy tones to cooler, atmospheric hues.

How to Mix Grays: A Step-by-Step Guide

This guide walks you through the process of mixing grays using watercolors and applying them with a fountain pen.

1. Choose a Base Palette

Begin by selecting the colors you want to mix. For example:

  • Warm Gray: Raw sienna (yellow) + French ultramarine (blue)
  • Cool Gray: Burnt umber (brown) + Primary blue
  • Neutral Gray: Red (e.g., magenta) + forest green

Each combination offers unique tonal qualities. For instance, raw sienna and ultramarine blue create subtle, natural grays, while magenta and green might yield more striking, moody tones.

2. Test on Paper

Swatch each color individually on your watercolor paper. This allows you to see how the pigments behave when activated with water and how they dry.

3. Blend and Adjust

  • Mix the two complementary colors on your palette.
  • For variation, try layering the colors directly on paper instead of fully pre-mixing them. This technique often creates a beautiful interplay of pigments as they dry.

4. Control the Temperature

  • Add more blue for a cooler gray.
  • Add more sienna or brown for a warmer shade.
    This balance is crucial when sketching urban landscapes or natural scenes to reflect the appropriate mood and lighting.

Using Fountain Pens for Line and Wash Techniques

Pairing vibrant custom grays with a fountain pen takes your artwork to the next level. Here’s why.

Fountain Pen as an Artist’s Tool

The creator demonstrates the versatility of using a bent-nib fountain pen for drawing. These pens produce varied line weights, adding dynamic texture and movement to sketches. When used with waterproof ink, such as Platinum Carbon Black, they allow you to layer watercolors over detailed linework without bleeding.

Sketching Quick Studies

Fountain pens are ideal for creating simple, fast sketches that capture the essence of a scene. For example:

  • Start with a 5–10 minute pen sketch of a landscape or urban view.
  • Use your custom gray mixes to add shadows, depth, and contrast.

This approach keeps the process enjoyable and pressure-free. As the creator suggests, "If it’s got a bit of life, a bit of sass, then you’re winning."

Real-Life Applications: Urban Sketching with Custom Grays

The creator highlights how mixing grays adds harmony and cohesion to urban sketches. By using the same colors throughout a piece - in varying combinations - you naturally create unity in your artwork. For example:

  • Mix warm grays for sandy tones in Monument Valley.
  • Use cooler grays for shadows under trees or in cloudy skies.

This technique is especially effective for landscape and urban scenes, as neutral grays rarely appear in isolation in nature. Instead, they carry subtle undertones of the surrounding environment.

Example: Monument Valley Sketch

In the video, the artist demonstrates how a limited palette of French ultramarine, vermilion, and a neutral gray creates a harmonious, vibrant sketch of Monument Valley. The red earth tones and blue shadows form a balanced interplay, while the custom gray mix adds depth to the piece.

The Joy of Experimentation

Art is as much about exploration as it is about creation. The process of mixing, swatching, and observing what unfolds on paper is liberating. The spontaneity of watercolor, combined with the precision of line work from a fountain pen, makes for a perfect pairing.

As the creator aptly puts it, "This is play. This is messing around. This is a time that you can give yourself just to be free and see what happens." The key is to embrace imperfection and look for the unique moments that emerge naturally.

Key Takeaways

  • Avoid Pre-Mixed Grays: Mixing your own grays yields more vibrant and dynamic results compared to using flat pre-mixed options like Payne’s Gray or Ivory Black.
  • Master Complementary Colors: Use pairs like blue and orange, red and green, or yellow and purple to create custom grays with varied tones.
  • Control Warmth and Coolness: Adjust the temperature of your grays by altering the ratio of colors in your mix.
  • Experiment Freely: Layer colors on the paper for unexpected effects, adding life and texture to your artwork.
  • Combine with Fountain Pens: Use a fountain pen with waterproof ink for detailed line work that complements your watercolor washes.
  • Stick to a Limited Palette: Reuse the same few colors in different combinations to achieve natural harmony in your sketches.
  • Play with Purpose: Enjoy the process without overthinking. The goal is to find joy and creativity in experimentation.

A Final Word: Embrace the Imperfect

At its core, art isn’t about perfection - it’s about expression. By experimenting with grays and embracing the quirks of mixing, you open up a world of possibilities for infusing your sketches with personality and depth. So grab your watercolor palette, your favorite fountain pen, and let the joy of creating take over. After all, as the creator says, "If it gives you a bit of joy, then fabulous. You’re winning."

Happy sketching!
