This is a black and white photo with colored lines added. Zoom in to see the lines. Your brain fills in the rest.
@trinsec may also have to do with the monitor used to view, size of image, etc. or just less effective for some colors...
@Tedgarrison3 @trinsec same for me on my iMac but works on the much smaller screen on my iPhone.
@rdaily
Yup, on my phone I'm starting to see the reds as well. But at that point it means the colored squares are a lot smaller, thus it's easier to fill in the blanks that way.
If the colored squares were the same size from the phone when displayed on a big monitor, it'd fill in the blanks better too. At that point you might as well just actually color the actual photos. ;)
@rdaily I see green and blue t-shirts on my iPad. Everything else is gray with lines on it.
Whoa!
@rdaily your Holodeck needs servicing
@rdaily For me it doesn't work very well for the reds. That's just a grey background with red lines over it. The greens, yelows and blues do a much better work of letting my brain fill in. The red might be too vivid there causing a too big contrast.
