Paint Color Picker

Pick the different color..

The far right color:: it requires combination of tertiary colors - all other all tertiaries - see below

Pick the different color..pallete green.jpg

The left-most color.

Courtesy of Photoshop, it is out of gamut.

It also is the only color that can be printed/painted without using yellow (or black) ink/dye.

Their respective CMYK values, left to right are:

C: 51 39 33 56 56

M: 60 93 39 45 61

Y: 0 37 90 92 37

K: 0 11 20 29 12

Both picks above are based on Deductive color model. (That is pertaining to colored pigments mixing).

But the answers are different..

Since the problem is more of screen pixel type (million colours), it would be clearer with Additive color model.

Note: copy/paste or file save may reduce a minimal value

Well, you named this "paint color."

Paint is formed of pigment, where CMYK is relevant.

In the RGB space, I didn't find any of them remarkable.

The rightmost color has RGB values that are not all multiples of 50.
Namely, 120 100 120.

All the others are multiples 0f 50.

Is that it?.

Yes, that is mathematically correct!

the title name is actually paint "color picker" .

Photoshop has that tool too?

note:file hint

[bonanova]

Photoshop has a "color picker" that gives values for a selected color in four representations.

• HSB = Hue/Saturation/Brightness (color wheel)
• RGB = Red/Green/Blue (displays - additive)
• CMYK = Cyan/Magenta/Yellow/Black (printer inks, in the order they are applied to the paper - subtractive)
• L,a,b = Lightness/two compressed CIE color space numbers.

It was in the CMYK space that the left-most color stood out from the others: Y=K=0.

In the additive RGB space, all values were multiples of 50 except R=B=120 for the leftmost color.

If you're asking which color paint is different in the sense I personally would never use it, it's still the left-most.

Still thinking about the clue.

When I saved from Paint as .jpg
the values are somehow changed to:
R 150 150 150 100 119
G 99 50 100 100 100
B 200 100 50 50 120
glitch maybe but the .bmp should be
R 150 150 150 100 120
G 100 50 100 100 100
B 200 100 50 50 120
One of them used a different value
for the same color: purple

It is a single exclusion problem.
Score ruling is applied..so grey it is!

What does single exclusion mean?
