Preview colours in Emacs-ESS
I accidentally managed to get colour names, #HEX, and a colour preview in Emacs. Don't have a bloody idea how, must've pressed some keybinding or menu item... But, now I can't seem to find where's that feature... I'm quite sure I wasn't hallucinating, so it's gotta be there, under some keystroke that I can't reproduce!!! =) ...
Changing UI color in Eclipse
I'm aware of this topic: I've used it to change most of the editor colors, and that's great. But that wasn't enought, there's still too much white (and I need to change it because it hurts my eyes). I've searched in the preferences (both using Eclipse itself and editing the files) for instances of while (255,255,255) and changed them a...
Override colorscheme
I often find myself wanting to change just something little in a colorscheme, but i don't want to edit the original file. I tried putting my change in '~/.vim/after/colors/blah.vim', but that doesn't work for me.

What is the target color profile in Image.FromFile?
I am curious what the useEmbeddedColorManagement parameter in System.Drawing.Image.FromFile actually does. This parameter directory corresponds to a GDI+ parameter in the same method of the same class. So debugging .NET source does not lead anywhere. If my understanding of color profiles is correct, a color profile is basically a mappin...
Android Color Picker
Does anyone know of a quick color picker widget that I could grab to use in my application? I've seen one in a few different applications that has a wheel with colors, and that you tap in the center to select, but I'm not sure where to find it. Google brings up nothing. Any color picker would be fine though. Thanks. ...
How does one convert 16-bit RGB565 to 24-bit RGB888?
I’ve got my hands on a 16-bit rgb565 image (specifically, an Android framebuffer dump), and I would like to convert it to 24-bit rgb888 for viewing on a normal monitor. The question is, how does one convert a 5- or 6-bit channel to 8 bits? The obvious answer is to shift it. I started out by writing this: puts("P6 320 480 255"); uint16_...
PHP: Convert shorthand Hex Colors to Regular

Colour instead of color?
I'm working on a game engine in C++ and I have methods like setColour and things that use british grammar. While I was thinking how C++ compilers mostly use the english language (correct me if I'm wrong) and how most APIs use american grammar, should I go with the flow and continue the unofficial standard in the grammar programmer high c...
Graph coloring Algorithm
From wiki http://en.wikipedia.org/wiki/Graph_coloring In its simplest form, it is a way of coloring the vertices of a graph such that no two adjacent vertices share the same color; this is called a vertex coloring. Similarly, an edge coloring assigns a color to each edge so that no two adjacent edges share the same col...

WPF global Controls color changes

CIE XYZ colorspace: do I have RGBA or XYZA?
I plan to write a painting program based on linear combinations of xy plane points (0,1), (1,0) and (0,0). Such system works identically to RGB, except that the primaries are not within the gamut but at the corners of a triangle that encloses the entire gamut. I have seen the three points being referred to as X, Y and Z (upper case) so...
