Liquitex BASICS Acrylic Paint, Phthalocyanine Blue

This product is best for: Beginners and students learning color theory and color mixing with acrylics. The thick, creamy texture supports peak retention for brushwork, and the satin finish offers a balanced sheen suitable for layering. It provides a solid pigment load in a standard 4-oz tube, making it ideal for building a dark blue swatch set without frequent restocks.
Why selected: It blends well with other colors, maintains brush strokes for visible texture, and offers reliable pigment density. The satin finish reduces glare on swatches, helping you compare tones accurately.
Caution: Some pigment may appear slightly lighter when applied in thin washes; test a small area first to gauge coverage and mixing behavior.
Apple Barrel Acrylic Paint in Too Blue (2 oz)

This product is best for: Quick, low-cost base coats and craft projects where a matte finish is desired. The small 2 oz size is handy for color swatch practice and projects that require frequent color testing.
Why selected: The 2 oz size makes it easy to mix with other shades to create a range of dark blues. Matte finish is useful for swatch cards where glare should be minimized for accurate comparison.
Caution: The smaller tube may run out faster on larger swatch sheets; plan accordingly if building a more extensive palette.
Apple Barrel Cobalt Blue (16 oz)

This product is best for: Larger canvases and base-color work where a true blue is needed across broad areas. The 16 oz size provides long-lasting coverage and is suitable for swatch collections that require consistent hue over time.
Why selected: A reliable, matte cobalt shade works well as a foundational color that can be mixed to achieve deeper dark blues without shifting hue.
Caution: May require multiple coats for opaque coverage on very light surfaces; test on your substrate before full-scale swatching.
20 Sheets Color Swatch Chart Kit

This product is best for: Professionals and students who need organized, portable color documentation. The kit includes 20 sheets with a practical size designed to pair with color sets that include up to 100 pigments.
Why selected: The rounded corners and durable design support daily use, and the grid layout aids precise color recording and comparison. It’s a practical reference tool for building and maintaining dark blue swatches.
Caution: This is a swatch-only product; it does not include paints or a palette, so plan to pair it with your chosen blues.
Buying Guide: Dark Blue Swatch Essentials
- Finish matters: Matte finishes minimize glare for accurate swatch matching; gloss finishes add shine but can obscure color perception in bright light.
- Consistency of pigment: Choose paints with strong pigment load for true color representation across layers and washes.
- Project size: For large projects, stock up on bigger containers to avoid color mismatch from batch variation; smaller tubes are ideal for swatch cards and practice.
- Finish vs. compatibility: If you work across mediums, ensure your swatch colors translate well when painted on different surfaces (canvas, paper, wood).
- Color planning: Start with a core dark blue (like cobalt or phthalocyanine blue) and mix with white or black to create deep, controlled swatch variations.
Frequently Asked Questions
- What is the best dark blue for acrylic swatches?
The Liquitex BASICS Phthalocyanine Blue is a reliable core for acrylic swatches due to its pigment load and satin finish. - Should I choose matte or gloss swatch paper?
Matte reduces glare and makes color comparison easier; gloss is better for final highlight accents but can reflect light unevenly. - How many swatch sheets should I start with?
Begin with 10–20 sheets to cover a range of hues; add more as your palette expands. - Can I use watercolor swatches with acrylic paints?
Yes, but note that color appearance may differ between watercolor paper and acrylic surfaces; swatch on compatible media when possible. - Is a large 16 oz blue better than multiple small tubes?
For large projects and consistent color, a larger container reduces batch variation and saves time; for experimentation, smaller tubes are convenient. - How do I maintain color accuracy in swatches over time?
Store swatches away from direct sunlight and extreme temperatures to minimize fading and hue shifts.
