I have a array of pixels. And I would like to Quantize them.
For Example
FF00FF,00FFFF stuff like that, but most are custom colors and are not a standard 256 color palette. So I need code to convert a color to a 256 color. I dont have any idea on how to do this, but thats why I came here. I do not want to use System.Graphics.Image.Palette or anything like that as this project uses arrays for images. I would like to if at all possible be able to convert a R, G, B color to 8bit, 16bit, 256bit and possibly use the HSL or NeuQuant method or something close to that, or maybe even some other methods of doing it. I do need to be able to do this for a single pixel, but I will also need a method for a array of them.

Is it possible to see the different colors (when using the graphics class) in a palette somewhere? It's hard to choose from the names only (DarkCyan, IndianRed ect, what is this!? )

I've got a chart showing data as a part of a vb.net forms application. The Chart object makes a really pretty picture, but I need it to match the color scheme on the rest of the UI. How do I get the RGB values for the palette?

This will sound an unusual question but I'm looking to find a way to reduce the number of colours of an image in a PictureBox from 1,000's to 15 and then apply a custom palette of 15 colours using a closest fit algorithm...
My graphics are never larger that 64x64 pixels generally, so the processing power / overhead needed to perform this operation is relatively small!
The inital algorithm I wrote is very slow and requires me to loop every pixel in the image and loop my palette doing a comparison to find a best fit colour.
Finding a decent method to do an initial colour reduction would be great!
I wondered if there were any inbuilt VB commands for PictureBox, etc that could be used to aid me in doing this...

Any code for creating the pallet for a Gray scale image, to display it on a picture box? I have written the code for creating for palette for a RGB image which is as follows:
Marshal.Copy(Image_bufffer, 0, _pImg, 1024 * 1024)
myBMP = New Bitmap(1024, 1024, 1024, System.Drawing.Imaging.PixelFormat.Format8bppIndexed, _pImg)
pal = myBMP.Palette
For i As Integer = 0 To pal.Entries.Length - 1
pal.Entries(i) = Color.FromArgb(255, i, i, i)
Next
myBMP.Palette = pal
Picturebox1.Image = myBMP 'Show the image
But the image displayed looks dull(less brightness) than the same image viewed from ImageJ. So instead of creating pallet from color.Argb, is there any way to create palette for a gray scale image?

I want the background of my form to be the same color as the window frame color that the user selects, even if that changes. I selected System->WindowFrame as my background color, but it always remains a dark grey, regardless of what I have my window color set to. How else would I achieve what I want? I assumed I was doing it the correct way. Do I actually need code that gets the system window color and then apply it?

I know that with some of the programs I use, when you click on an item to change it's color, the color dialog will actually show the current color and it's rgb value.
I'd like to do that in my application but can't find the answer on how you do it.
To change the backcolor on a textbox, the user double clicks the box and it shows the color dialog.
I think I have all the properties set right -- fully open to show custom colors etc.
BUT, it doesn't show the current color.
They all have 0 0 0 rgb.
