Title: Two different colors?
Post by: hidden on May 30, 2010, 03:16:45 PM
Do you remember the classic checker board with two different tones of gray that at the end are the same tone?
Well I found three new examples. Impressive!

Can you believe that upper gray is the same as the bottom one?


This is amazing:

A = B? It's hard to believe...  :ss-shocked:



And last but not less:

Color Star A = Color Star B

I'm wondering, why always gray...? Does it work with other colors? The stars are blue, I will try with red and will tell you...

Well.  The first pic is close but not quite the same.
The little box on the left has the top and bottom colors.

The second pic is DEAD ON.  Had to test them because I was amazed by them!

The third, the stars are not the same color but are the same size!  Wierd.

Something is happening with your test Sami, on my Photoshop, the grays are 102, 102, 102 on both images.
Probably the problem was when I saved them with "Save for Web" option after checked, just to make them less heavy.
On your test, you might had selected a random pixel slightly different than the others. An image, after repeated saves with different programs, can result corrupted. You've got completely another numbers for RGB... even for the second image, where they resulted be the same. :ss-shocked:

BTW, the stars ARE also the same blue: (and size)  (R51, G51, B102)


(Sorry for the grammar, I rewrote the above paragraph ten times without find the correct way...hope you understand)

Well, I tried the stars with a dark red (brown? R102,  G0,  B0) which is the darkest pixel found in the lighted background and the effect is also evident...
