Second, in terms of color, I also consider to use #f5f5f5 white with hint of light grey instead pure white #fffff for the background and Dark Blue #1D3354 for the text. There were reasons for this decision. The Dark Blue color, I took it from the Freightsight color identity. I avoid to use pure black #00000 for the text and pure white #fffff for background, as the recent research on readability found that using pure black on top of pure white background can cause eye strain to the reader when user read the text over an extend period.

Although the real problem is not always because of the black as text color. Black color in fact can be good for small thin fonts such as body text. A background that is too bright such as #fffff pure white can also be a major contributor to digital eye restrain since its too bright. Pure white has 100% of color brightness while pure black has 0% color brightness. Thus disparity in color brightness creates intense contrast light levels that can overstimulate the eyes when reading text.

A research study on Reading and Myopia found that black text on white background overstimulates the OFF ganglion cells white white text on black backgroudn overstimulates the ON ganglion cells which means white text from a black screen could inhibit myopia while black text on white background may stimulate myopia. The study advises against reading text on white background due to the significant contrast polarity.
