The Colour Contrast Analyser enables you to pick colors on the page, and review their contrast thoroughly. However, be sure to only use the up-to-date "luminosity" algorithm, and not the "color brightness/difference" which is outdated. You can also use Snook's color contrast tool, which is entirely up-to-date as of 11 January 2015.
The Farnsworth–Munsell 100 Hue Color Vision test is a color vision test often used to test for color blindness.The system was developed by Dean Farnsworth in the 1940s and it tests the ability to isolate and arrange minute differences in various color targets with constant value and chroma that cover all the visual hues described by the Munsell color system.

Google Chrome has a color contrast debugger with visual guide and color-picker. The downloadable software Color Contrast Analyser enables you to pick colors on the page, and review their contrast thoroughly. However, be sure to only use the up-to-date "luminosity" algorithm, and not the "color brightness/difference", which is outdated.
Most colors doesn't have enough contrast with the background, according to W3C's Colour Contrast Analyser. Text or diagrams and their background must have a luminosity contrast ratio of at least 5:1 for level 2 conformance to guideline 1.4, and text or diagrams and their background must have a luminosity contrast ratio of at least 10:1 for ...
A photograph color graded into orange and teal, complementary colors commonly used in Hollywood films. Color grading is a post-production process common to filmmaking and video editing of altering the appearance of an image for presentation in different environments on different devices. Various attributes of an image such as contrast, color ...
Color targets such as the ColorChecker can be captured by cameras and other color input devices, and the resulting images’ output can be compared to the original chart, or to reference measurements, to test the degree to which image acquisition reproduction systems and processes approximate the human visual systems.
Contrast is the difference in luminance or color that makes an object (or its representation in an image or display) visible against a background of different luminance or color. [1] The human visual system is more sensitive to contrast than to absolute luminance; thus, we can perceive the world similarly despite significant changes in ...
Snook's Colour Contrast Check provides a comprehensive check of whether a particular choice of foreground and background colours meets WCAG 2.2 standards for brightness difference, colour difference and contrast ratio. You can find the text colour and background colour as a hexadecimal value by using the "Inspect element" function that most ...
