Tools
- Developer tools that get and calculate values from code
- Eye dropper tools
- Tools where you enter values into a field to compute
- Tools that compute nearby colors that comply
When to get contrast values from code
- Whenever code values are available use those
- Consider opacity/transparency though
When to use eye dropper
- for image of text
- for text over background image
- for text over gradient
- Contrast in certain browsers may be adjusted
- anti-aliasing may produce untrue colors -- so be sure to grab the correct color
- eye drop from the source rather than an image as image compress may distort colors.
Other things to consider
- Contrast may change with zoom or responsive views
