To date, most e-ink displays are available in white or black. They are still black. The advanced color ePaper (ACEP) technology was announced by the e-ink corporation in 2016, and some eBook readers are beginning to use color e-ink displays. Because of the lack of backlit, e-reader companies have solved the problem of illiteracy in the dark by using a technology that extends from the top of the display, rather than under the so-called front-lit display.

In conclusion, the e-ink display is designed for use in eBook readers, not phones and tablets, so the text is in print and very readable. If you do not have the above-mentioned weaknesses, you will not be able to reflect light in the sun. Battery life is a feature we want in our current smartphones.
