Precise Lab Color

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.

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.

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.

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

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

I copied the sleeve and that resulted in a difference of color on the right side.
Normally I will use the healing brush to fix this, but because the jacket has really tiny "rounds" in the febric, this will not work this time...
Does anybody has a solution for this?

I also wanted to erase the creases on the right side of the button, but again, the healing brush is not my friend...

Help?

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?

I am going to re-paint my motorcycle and I dont know which color I should color it. Thats why I am looking for a person with some color-eye which can help me decide the color. I will pay 30$ for the best image. I want to color the wheels, plastic parts (idk. The name in English but the "Covers") and the metal parts bars etc. Ofc. You can also edit other parts which you think would

Hello,
I wondered if someone would hear me out and possibly help or advise me.
In the attachment there is a great picture of a bass jumping with the sky and sunset in the background.
I added a white paw to the sky and hope to make it look or blend in as a beleivable cloud in the sky.
My novice thoughts about how I might do this was as follows:
1) create and save a precise selection of the paw with a close detailed trace (I am having trouble donig this ste) and save the selction.
2) take that selection to the background copy layer and delete all the area inside that selection
3) take the background copy for cloud breakthrough layer and place it below the background copy layer with color enhancements to show through the holes in the background copy layer.

there is also a cloud paw layer which I aborted efforts working with.

-Bottom line is I am looking for a cloud paw in the sky which looks good, an orange emphasis is desired.

If you can do some work in the file and post it back up or at least advise how you would reccomend I try and go about it would be greatly appreciated.
BTW - The selection process really giving me fits with the idea I had, If you know of a great selection tutorial please send me some info.

Thanks,
Joe

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,
