Adding standard light mode theme

[mateuszdrab]

Hi @JuanMTech

Thanks for this cool theme, looks really well on OLED devices like my Razer Blade.

I forked the theme and tried to move all the custom properties into the dark mode section of a Home Assistant theme so that during the day, standard light mode is shown. However, after doing so, the cards and the background lost the black color. Having had a look at the dev console, I can see that the primary-background-color is #111111 and not #000000.

Are you able to take a look why that happens? Do you think it's a HASS bug? I expected the shift not cause any differences as I understand both dark and light mode sections can override all properties.

My fork is at mateuszdrab/amoled_blue

Thanks
Matt
