On iOS, Settings/General/Accessibility/Display Accomodations/Color Filters. There even filters for specific types of color deficiency, or modify to taste.

A lot of video games have filters now for things like friendly/enemy tags and such.

This exists in Android. Greyscale mode is implemented with the very same color-shifting functionality.

It's usually under Developer Options.

I've been on this for a few weeks now and has made a huge difference in compulsively checking email and twitter. Pro tip: add it to the triple home button click (Settings>General>Accessibility>Accessibility Shortcut (all the way at the bottom)>Select 'Color Filters') for easy switching for color/grayscale.

It's weird, I have "invert colors" but not any other options. I'm on Marshmallow (samsung s5)

I just went through this on my S5.

"Here's a solution! Go to "about device", find "build number", and tap it a bunch of times until the phone tells you you are a developer. Then, go back to settings, and above about device, you will see a new option called "developer options". Open it, and find "Simulate color space", and set it to "Monochrome"."

Why do grey pixels consume less power than red pixels of the same brightness?

In fact, assuming (maybe wrongly) that your phone screen's colors are created from RGB, CMYK or some other combination of primary color 'dots' in each pixel, grey would require lighting all the dots in a pixel, while 'redscale' would limit power usage to 1/3 or 1/4 of the dots. I realize there are many other issues potentially involved, but perhaps someone could explain.

EDIT: Sorry, the correct terminology of 'dots' and pixels is lost in my brain someplace and I don't have time to find it.

On my Android phone: settings->developer options->advanced->simulate color space, which has simulation of 4 varieties of colorblindness. Developer options has to be enabled by finding the kernel build number in the "About" page of settings, and tapping on it about 7 times.

Separately, I've got a "Night Mode" setting, which lets me set a schedule and a color temperature to use.

Worked for me, thanks!

BTW, I had to vouch for your comment to get it to not be [dead].

I've used Sim Daltonism[0] for some stuff at work. I've only used the Mac version, but looks like there is an iOS version, as well.

Display technologies that light up are all based on RGB, as far as I know (additive color). Printers and such, which use subtractive color, would use CMYK.

What takes more power depends on the hardware. An OLED display would take more power to light up a pixel than to keep it dark. An LCD display would typically take slightly more power to show a dark color. The backlight is always shining (which takes most of the power), but darkening an LCD pixel takes more power than just letting the light through does.

Maybe the actual power savings would come from lighter rendering calculations (only having to calculate a single color channel)?
