Top 15% of character readability issue on white backgrounds. #55

When viewing the font on a white background on an average consumer grade device, the top of the characters seem to prematurely fade into the background color. On the opposite side of the spectrum, if using a black background, the premature fading is not apparent and the characters are very clear and distinct; no premature fading on either the top or the bottom of the character.

I understand that is not an issue with "the font" and is for the most part a visual perception of the rendered font is subject to the user, the user's device and device color settings. Most consumer grade devices do not have the best control of brightness and contrast and obtaining a linear spectrum of a color from 0 to 255 is quite difficult is not impossible. The actual linear spectrum is probably more in the range starting at 10+/-5 to 245+/-5.

I do not know anything on font design, but is there any way increase color value used in the anti aliasing of the top of the character to resemble that of the anti aliasing pattern used in the middle and bottom of the character?
