Color Science Fundamentals
Before diving into testing methods, understanding basic color science helps you make sense of specifications and test results. This knowledge is essential for interpreting color accuracy metrics.
How Monitors Create Color
RGB Color Model
Monitors use additive color mixing with three primary colors:
Red (R)
0-255 values
Green (G)
0-255 values
Blue (B)
0-255 values
Key Color Metrics
Color Gamut
The range of colors a monitor can display, usually expressed as a percentage of a standard color space. Wider gamuts can show more saturated colors.
Color Depth (Bit Depth)
The number of bits used per color channel. 8-bit = 16.7 million colors, 10-bit = 1.07 billion colors. Higher bit depth reduces banding in gradients.
White Point
The color temperature of white on your display, measured in Kelvin. 6500K (D65) is the standard for most color work.
Gamma
The relationship between input signal and luminance output. Standard gamma is 2.2 for most applications, 2.4 for video in dark rooms.
Understanding Color Spaces
Color spaces define the range and interpretation of colors. Knowing which color space you need is crucial for selecting and testing monitors for your specific workflow.
Common Color Spaces Explained
sRGB (Standard RGB)
The baseline color space for web and general use.
- β’ Coverage: Smallest gamut, but most compatible
- β’ Use: Web design, social media, general photography
- β’ Target: 100% sRGB coverage minimum
Adobe RGB
Wider gamut for professional photography and print.
- β’ Coverage: 35% larger than sRGB
- β’ Use: Professional photography, print design
- β’ Target: 95%+ Adobe RGB for pro work
DCI-P3
Cinema standard, increasingly common in consumer displays.
- β’ Coverage: 26% larger than sRGB
- β’ Use: Video production, HDR content
- β’ Target: 90%+ for video work
Rec. 2020
Ultra-wide gamut for future HDR content.
- β’ Coverage: Theoretical maximum for displays
- β’ Use: High-end video, future-proofing
- β’ Target: 70%+ is excellent
Quick Color Space Selection Guide
Choose sRGB If:
- β Primary output is web/digital
- β Working with typical clients
- β Budget is a concern
- β New to color management
Choose Wide Gamut If:
- β Professional print work
- β High-end photography
- β Video production
- β Future-proofing investment
Delta E: Measuring Color Difference
Delta E (ΞE) is the industry standard for quantifying color accuracy. Understanding this metric is essential for evaluating professional monitors and interpreting calibration reports.
Delta E Scale
Imperceptible
Perfect color match, indistinguishable to human eye
Barely Perceptible
Only noticeable to trained eyes in direct comparison
Noticeable
Visible difference but acceptable for most work
Significant
Obvious difference, unacceptable for color-critical work
Professional Standards:
- β’ Print Industry: ΞE < 2 required, ΞE < 1 preferred
- β’ Photography: ΞE < 3 acceptable, ΞE < 2 preferred
- β’ Medical Imaging: ΞE < 1 mandatory
- β’ Consumer Displays: ΞE < 5 typical out of box
Testing Color Accuracy Without Calibration Tools
While professional colorimeters provide the most accurate results, you can perform meaningful color accuracy tests using free resources and visual assessment techniques.
Visual Test Methods
1. Reference Image Comparison
Use standardized test images with known color values:

- β’ Check gray neutrality (no color casts)
Tip: Use our color accuracy test tool for standardized patterns.
2. Gradient Smoothness Test
Reveals bit depth limitations and color processing issues:
What to Look For:
- β’ Smooth transitions
- β’ No visible banding
- β’ Even color progression
- β’ No sudden jumps
Problem Signs:
- β’ Visible steps/bands
