I went to achecker.ca to test my website for accessibility issues. While it found no actual problems, it found about 100 potential issues. One of them is this: 1.4 Distinguishable: Make it easier for users to see and  hear content including separating foreground from background. Success Criteria 1.4.1 Use of Colour (A) Check 86: script may use color alone.  Line n, Column n: <script async src=http://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js></script>This potential issue refers to all internal and external javascript on my site including google adsense script.My question is, do I really need to specifically define a default color for such elements or is this tool a joke?
Does a script tag really need a color defined?
