0021-axe-01: An Example of Performin the Check with axe DevTools
Confirm that the issue Elements must meet minimum color contrast ratio thresholds （要素は色のコントラスト比（最低限）の閾値を満たしていなければなりません）is not reported by axe DevTools.
Note that no issue is reported in the following cases, even when the guidelines are not met.
When the contrast ratio is insufficient after the text and/or background color change, e.g. after mouse hover
When the contrast ratio of large-scale text is 3:1 or more and less than 4.5:1
While large-scale text is defined as 29px(22pt) or larger font, or 24px(18pt) or larger bold font within freee’s product as the primary text is assumed to be in Japanese, WCAG defines it as 18pt or larger font, or 14pt or larger bold font assuming euro-languages. As Axe DevTools is based on the requirements set by the WCAG, it cannot detect insufficient color contrast of Japanese text whose font size is between 18pt and 22pt (14pt and 18pt if bold).
When the contrast ratio of non-text content is insufficient.
icons, images, images of text, outlines of buttons and input fields, etc.
Insufficient contrast ratio of the actual colors being seen, when different colors appear to blend into a new color due to overlapping translucent elements.
When it is difficult to identify the background and foreground colors in overlapping elements.
