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 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
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?
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 want to change orange color to red color.
I use Magic Wand Tool to select orange color and Paint Bucket Tool.
But edges not smooth.
Can anyone suggest me the best way to change color ?
Thank you
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?
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 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
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,

i have a color sample in L,a,b mode used as 3d coordinates. I also know the coordinates of a few other colors (A1,A2,A3,etc) of which A1 and A2 are the closest. A2 in this case is the closest one. how should i measure how many percent of A2 color should I mix with A1 color to get the best match (lowest delta E)? are those dashed lines correct method?
A1 L:85 a:3 b:8
A2 L:80 a:5 b:13
Sample L:81 a:4 b:9
Hello! I'm making a poster for silk-screening. Each color needs to be on a separate layer so that each color can be hand-printed one at a time. Foolishly, I did not draw the colors on separate layers. I need a layer for the white outline, a layer for the purple, and the remaining layer the black (which will just be the color of the paper for those familiar with silk-screening). Posterizing doesn't seem to work, and selecting color range doesn't seem to nail it exactly either. I would greatly appreciate any help.
I am attaching the PSD file. Please do not reproduce this image (though i don't know why anyone would!)
