NativeBannerView text themes are not changing to black

[kardenvan7]

Hello! I recently tried to implement native ads using NativeBannerView. But I found out that titleAppearance, domainAppearance, bodyAppearance and callToAction text colors can not be set to black and shades of grey programmatically. Changing these styles to other colors works as it should. I've tried to change these colors by using NativeTemplateAppearance but it seems to do absolutely nothing. Is this a real thing or am I simply doing something wrong?

P.S. Looks like it works incorrectly with darker shades of gray and black colors. I tried to get #FF222222 (which is dark grey) and the color of text was very very light grey. Which leads me to think that #FF000000 changes the setting but gives white text instead of black.

My code:

Hello! We can’t reproduce this problem. In our sample, your appearance setting banner looks as expected. Which version of SDK did you use? If it’s possible, send a broken app example to mobile-ads-github@yandex-team.ru.
