what is the best way to find which color on one picture is closest to some palette of color shade?anything better than color range tool with tolerance?

Hello,
I am new at this so thanks for helping me out. I am making a fiber art portrait from a photograph. I need to duplicate the colors in the photo with fabric. I know in Corel you can select the eyedropper, click on the image, and produce a sample of the color to then print out and take to the fabric store to match. I have spent the evening trying to do this in Photoshop. I have used the eyedropper, used the 3x3 pixel, get the circle with the color, but cannot figure out how to drop them somewhere to then print out to take to the fabric store. Is is possible to do that? Any other suggestions if not? It's a total of about 6 colors as I have applied the Posterize feature. Thank you.

hello.i'm looking for the most accurate color selection method in photoshop for L,a,b color mode. what i want to achieve is to know the values for L,a and b that would let me enter those values to excel file which will tell me which shade is the closest. so those shaders values are the most important. thebestcpu said:
if you use a PS tool that uses the tolerance option, it has inherent limitations as such a tool selects on an RGB math equation that do not exactly reflect what you see with you eyes (e.g. it is color data based not luminosity based. That means the blue component of RGB in selecting an area gets too much weight.


so which tool works well on Lab color mode?
how would you get the Lab values from those shaders to be accurate? the tooth neck part is the most intense color because of thickness while the edge is the most transparent.
1) should i wand select the whole shader (without white blow out spots) and filter -> average?
2) should i pick the color from 1/2 or 1/3 height? maybe i should draw a horizontal line and select 1 point for each shader in the middle of it's long axis?
look at D3 and D4 how short color range it is.

this photo should be taken with gray card to set the white balance correctly.

I am trying to find software or a tool or plug in that allows a large folder of images to be sorted by color/hue. The closest thing I have found is Google Picasa but you can only do one color at a time and it only has a few choices. Thanks, Cindy

We have a project where the final media will have a color palette limited to 454 colors. We have a conversion from the media's color selection to RGB. So, from an XML file I created a CSV file, meaning I have both if necessary, of 454 colors with a name and their RGB values.


I need to create a color library so that I can put an image in photoshop and then change it to indexed color so that it ONLY uses these 454 colors.


Is there a way to convert or compile my csv/xml file to a photoshop ACT file? I feel like there must be. I do *not* want to enter 454 colors by hand.


Thanks so much for any advice. Attached is a screenshot for reference.

I am trying to replace the background color of the image below. I am using the replace color tool. I use the first eyedropper tool to select the color. Then the second eyedropper+ tool to select the shaded area. I use a fuzziness of 50-70. I enter the replacement color using a color code. The color is replaced, however the final result is a slight different color than the color code I enter. When I check the end result using the eyedropper tool, I can see a different color code. Why does this happen? What other method can I use to replace the color with a specific color? Thanks

So I'm trying to get the black on this hood, to match the rest of the car. I'm not very skilled with photoshop but I did a ton of things on it already just can't do color stuff.

Would someone mind matching the colors for me real quick? I would greatly appreciate it!!

Hi all,

Having trouble with this problem...

I have layer 1 with a color mask set to black, red, blue etc.
I have layer 2 with a color mask which i want to match and also become black, red, blue

There are hundreds of files, and the color in layer 1 is always different.

Manually i would simply click on the layer 2 mask which opens the color picker, and select the area of layer 1 i want to match.

But doing that in a macro does not work.

I can't get a macro to recognize that i want to copy the color content of a mask, and not the specific color used in the example during which the macro is recorded. The color picker does not seem capable of selecting a dynamic input (e.g. whater color is on layer 1), it simply copies whatever was in layer 1 during recording like a dumb instrument.

thanks for any input.

i'd like to recreate such color in ps. those values are measured by American Dental Association Laboratories and are precise, but the difference between samples is very low (L: 65,73 or 67,21)
1)how can i create such precise color is ps?
L:66,33
a:0,3
b:8,73

when i eyedropped my samples i had 16 bit values of the same sample like this:
L:26975
a:567
b:1339

2)why the difference is so huge?

I'm working on a tutorial and it calls for snowflake custom shapes, which I downloaded from Deviant Art. I set the color, using the same color code they recommended. The shape comes out red. Red, no matter what I do. I tried other shapes and they're all red. Mode is set at RGB color and 16 bits/channel. Can somebody tell me what is causing this? BTW I tried it on another image and it was gray (still not the right color.
Thanks,
pslane
