Chroma is a lightweight AOSP ROM focused on battery, performance and stability.
The philosophy of Chroma is to stay relatively close to Google's stock Marshmallow with the additions of essential features that should have been included with stock Marshmallow as well as providing the most up-to-date security patches.


Modified version of hellsgod's HellsCore kernel
Layers support
Native LED notifications (solid, limited to RGB colors)

Status Bar Customization:
Battery Style (Icon Portrait/Landscape, Circle, Text, Hide) and Battery Percentage
Clock & Date (Show/Hide, Color, Alignment, AM/PM, Show/Hide Date, Date Style, Date Format)
Brightness Control (long press status bar to change brightness)
Double-tap status bar to turn screen off
Show/hide notification count
Quick pull-down on left/right side to pull down tiles
Network traffic
Pressing on clock or date on status bar opens up Clock, Calendar
Status bar weather
Show/hide brightness slider

Navigation bar customization
Navigation bar height
Kill app back button
Double tap navigation bar to sleep
Clear all recents button (swipe down on recent apps and it'll display on the bottom right)

Lock screen customization
Lock screen wallpaper
Power menu customization (power off, reboot, screenshot, airplane mode)
Advanced Reboot (reboot/soft reboot/recovery/bootloader)

Volume rocker customization:
Wake device with volume keys when screen off
Long press volume up/down keys to skip track when screen off

A large number of optimizations, memory leak fixes, security patches
Long press recents to swap back to previous app
Prevent camera shutter sound
... and more (see changelog)

Special thanks to:
  • People who have tipped/donated to me to support ongoing development
  • hellsgod for the kernel
  • Sykopompos for being a good friend
  • CyanogenMod as well as the open source community

Pre-requisites: unlocked bootloader | latest TWRP recovery

2. Boot into TWRP recovery.

Pffft, technically my reserved posts are first ;)

Amazing ROM. Special thanks to everyone behind this project !

It's just me, Syko and some freelancing graphics from @boysetsfire. I'm doing all of the feature sets, thread maintaining and Syko is just being a build bot for devices other than the shamu (Nexus 6). @boysetsfire helps me make cool bootanimation and wallpapers

Hope the experience on mako is just as buttery smooth as the shamu variant.

Was waiting for this. Flashed today morning (I'm in India, I flashed the moment it was available ;)).

Thanks @sykopompos and @zephiK for this awesome ROM. It's running great.

The build is too good to be just a second build (but isn't that the thing for which @sykopompos is known ;)). Few glitches are there but they are manageable:
1. Can't see Home option (to select launcher) in settings
2. Wallpaper can not be changed.
