Using the RGB Color Palette

Using the RGB Color Palette

            Photoshop, Illustrator, or CorelDRAW: all three use a palette of some sort. Normally, you would choose colors based off the palette. This can involve a lot of trial and error while trying to get the colors you want for the image to come out perfectly. Though most of the time - due to monitor issues or incorrect settings - this does not work out.

            Today we want to discuss how to effectively use the RGB palette offered in the Condé support area, our PartnerNet:

            Once you download and unzip the particular color chart for your program, even if you simply get the JPEG formatted one, you will find we have provided quite a large group of files.

            Each file has a name scheme of “RGB_15s_B###”, the ### representing a particular number. Starting from B000 to B255, each in increment of 15, encompass the whole RGB spectrum, along with an extra file to show the RGB grayscale.

            So to start, choose the B000 file, and open it.

            Once opened you will see grids of colors, numbers along each edge, and a blue value listed at top of 000. This value corresponds with the file naming system, the file ending in B000 means the blue value of every color in this file will be 000. Red Value is along the top and bottom, and green is along each side. So starting from the top left, the RGB of that box is – 255, 255, 0 – and on the bottom right the value of that box is – 0, 0, 0.

            Now if we started counting from the top left, when 5 boxes over to the right, and 3 boxes down, the box value would be – 180, 210, 0 - we can figure this out easily because 5 boxes across the value for red for anything in that row is red 180, and 3 boxes down anything going across that row has a green 210, and since every box in this chart has the same blue value of 0, we can find the code for that particular color.

            With the simple part done, let’s do something a bit harder - find the file ending in B120. Starting from the top left, count to the right 6 times, and down 7 times. Now with what we learned on the last file, we can find the value for this file the same way. The 6th row to the right all have a red value of 165 going down, while the 7th row down all have a green value of 150 going across, and all boxes have the same blue value on this file of 120. Meaning this particular box has an RGB value of 165, 150, and 120. Now that we know how to find the values, let’s find out how to use them properly.

            Any program you use normally have a color input or a place to choose a color palette; with a little training with the program you can easily find out how to input the particular RGB color you’re looking to use.

            Now that all this is done its time to move onto the best thing to use the color charts for: consistent results. Make sure your settings are correct and print out charts, you don’t need to do all charts, doing every other one or so is normally enough. Once printed, press them onto a common substrate you work with, like polyester fabric or coated metal. Once pressed you’ll see the exact output and look of the colors, this is important, because now you know what a particular color will turn out looking like before you ever print it, no matter how the color looks on your screen.

            Hopefully this has helped, if you need further assistance or aid in anything with this process, please give us a call: Conde Tech Support 1-800-826-6332, option 2.

            Thank you for your time.
