Actual Result

• The Informative image "X"  close buttons present in "Column", "Save as", "Share", and  so on Modal dialogs having the insufficient contrast ratio.

           Foreground:#C7C7C7
           Background:#FFFFFF
           Ratio           :1.7:1

This will make it difficult for low vision users to discern meaningful graphics that have insufficient contrast.

Expected Results

For all informative images, ensure that the contrast between foreground, background or adjacent colors is 3:1 to make the image's information accessible for users with low vision and color-blindness.
