I wanted to to print one single line in a different color. Use ANSI Escape Sequences. Windows before 10 – no native support for ANSI colors on the console For Windows version below 10, the Windows command console doesn’t support output coloring by default. You could install either Cmder, ConEmu, ANSICON or Mintty (used by … Read more
The ANSI escape sequences you’re looking for are the Select Graphic Rendition subset. All of these have the form \033[XXXm where XXX is a series of semicolon-separated parameters. To say, make text red, bold, and underlined (we’ll discuss many other options below) in C you might write: printf(“\033[31;1;4mHello\033[0m”); In C++ you’d use std::cout<<“\033[31;1;4mHello\033[0m”; In Python3 … Read more
The specific numbers in the question are from CCIR 601 (see Wikipedia article). If you convert RGB -> grayscale with slightly different numbers / different methods, you won’t see much difference at all on a normal computer screen under normal lighting conditions — try it. Here are some more links on color in general: Wikipedia … Read more
Here is an extension method that overloads the AppendText method with a color parameter: public static class RichTextBoxExtensions { public static void AppendText(this RichTextBox box, string text, Color color) { box.SelectionStart = box.TextLength; box.SelectionLength = 0; box.SelectionColor = color; box.AppendText(text); box.SelectionColor = box.ForeColor; } } And this is how you would use it: var userid … Read more
You should use: holder.text.setTextColor(Color.RED); You can use various functions from the Color class to get the same effect of course. Color.parseColor (Manual) (like LEX uses) text.setTextColor(Color.parseColor(“#FFFFFF”)); Color.rgb and Color.argb (Manual rgb) (Manual argb) (like Ganapathy uses) holder.text.setTextColor(Color.rgb(200,0,0)); holder.text.setTextColor(Color.argb(0,200,0,0)); And of course, if you want to define your color in an XML file, you can do … Read more
I’m assuming that’s an ARGB code… Are you referring to System.Drawing.Color or System.Windows.Media.Color? The latter is used in WPF for example. I haven’t seen anyone mention it yet, so just in case you were looking for it: using System.Windows.Media; Color color = (Color)ColorConverter.ConvertFromString(“#FFDFD991”);
If your terminal supports it, you can use ANSI escape codes to use color in your output. It generally works for Unix shell prompts; however, it doesn’t work for Windows Command Prompt (Although, it does work for Cygwin). For example, you could define constants like these for the colors: public static final String ANSI_RESET = … Read more
Here’s a correct table of percentages to hex values for opacity. E.g. for 50% white you’d use #80FFFFFF. To think in terms of transparency instead, flip the order of the percentages (more opaque = less transparent). % Hex 100% FF 95% F2 90% E6 85% D9 80% CC 75% BF 70% B3 65% A6 60% … Read more
How to change the color of an svg element?
Garry Tan posted a Javascript solution on his blog (which he attributes to a now defunct mjijackson.com, but is archived here and the original author has a gist – thanks to user2441511). The code is re-posted below: HSL to RGB: /** * Converts an HSL color value to RGB. Conversion formula * adapted from http://en.wikipedia.org/wiki/HSL_color_space. … Read more
