As an aside, previously my background color was = =E2=80=98antique white=E2=80=99 now it is =E2=80=98gainsboro=E2=80=99. = Back to here. The columns according to how I interpret them: 1. text on color bar, this is the background-color, and the text is = unreadable at line 1 (black on black) 2. the same color as foreground-color, the black text is readable on my = normal background color 3. the RGB hex values I am saying the problem is in column one where WYSIWYG background-color = and text color are identical it is unreadable. And, in cases, such as blue, medium blue, the column one=E2=80=99s = presentation is difficult to read the black text. >> I=E2=80=99d like to suggest color contrast arcs through a distorted = triangle colorspace for choosing textcolor always in contrast to the = background color for easy reading. In the case of black, blue, medium = blue background the text color is white.

I=E2=80=99m suggest in column one, where the black text is too close to = the background-color being demonstrated, such as blue, medium blue, that = the text-color in column one should be inversed to white from black.=
