Indexed Color Conundrum

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.

Hi,

I have to generate images of combinations of two hair colors. There are 15 total colors, so that means 225 total images.

I was hoping to shoot photos of each of the colors without overlays, then photos of the overlays. I'd like to make the overlays (which do not cover the entire image) into individual layers and then use them over the base colors. I want the blending to look realistic, and so I need transparency that is accurate.

Any thoughts on how to do this would be appreciated.

Thanks!

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.

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!!

I'm taking pictures of a product 360 degrees and noticed small variations of light and color and want to equalize between all images.
I do not want to apply the same effect at all, so I do know the Automate.
I want to adjust all the photos based on a standard photo with adjustable pre-defined levels and colors.
If you can do this with a batch command would be better.


See the three images has a small variation in the light which can be seen in the background of the image. I want to equalize it between all images.

Sorry my english, I'm from Brazil.

Thank you

Hi all, I'm new to the forum and I'm a freelance researcher in image editing.
I'm italian, so sorry in advance for my english .
I'm also a little crazy , I left my job as employee 'cause I believe in my researches and I want to make them my only job.
I developed a new effect for substituting colors in images. I would like to test the goodness of this new approach useful for retouching photos ... so I ask you a little collaboration, if you want to help me, you should retouch the image that I attached in this way: change the color of the pen fromred to white.
It's important to me to know how much time you spent in retouching the image and what applications you used for achieving the result, so please post the altered image together with the requested info. In a few days I'll post the image elaborated with my algorithm.
Really thanks to all, in advance, for the collaboration.

Guys, I could use your input. I created the attached poster for a sports ministry at church. I like my idea (taking my Bible verse and making it a double meaning), but what I am uncertain about are the colors. Because the design contains silhouettes, naturally I used black and white. However, can a black and white poster attract church members' attention on a bulletin board? I like simplicity, not sure about others. Can you please let me know if you would recommend that I color this poster in any other way? Feel free to color this and show me what you've done. Please, I really need your opinion. I have never done this before.

I'm not talking about the polaroid texture, but the colors, this grey color and stuff. Anyone?

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!)

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
