The Luminous theme for MIUI V4 has seen an update today. It has now reached to version 1.2. The theme is now fully black save some exceptions here and there. The original creator of this dark theme with amazing luminous icons is Treason Yu from China. When I applied it on my device I was shocked to see the lokscreen borrowed from the ANGL theme by Jumba which was in grayish-blue and did not match the theme. So, I changed it to circular black and white LS from the previous version of the same theme. The LS also shows weather updates if you install MIUI Weather app on your device.
