How to Get It

Basic Usage

using System;
using System.Drawing;
using Console = Colorful.Console;
...
...
Console.WriteLine("console in pink", Color.Pink);
Console.WriteLine("console in default");

Basic Example

Write With Full System.Drawing.Color Support

int r = 225;
int g = 255;
int b = 250;
for (int i = 0; i < 10; i++)
{
    Console.WriteLine(storyFragments[i], Color.FromArgb(r, g, b));

    r -= 18;
    b -= 9;
}

Format Text Using Two Colors

string dream = "a dream of {0} and {1} and {2} and {3} and {4} and {5} and {6} and {7} and {8} and {9}...";
string[] fruits = new string[]
{
    "bananas",
    "strawberries",
    "mangoes",
    "pineapples",
    "cherries",
    "oranges",
    "apples",
    "peaches",
    "plums",
    "melons"
};

Console.WriteLineFormatted(dream, Color.LightGoldenrodYellow, Color.Gray, fruits);

Alternate Between 2 or More Colors Based on Number of Console Writes

ColorAlternatorFactory alternatorFactory = new ColorAlternatorFactory();
ColorAlternator alternator = alternatorFactory.GetAlternator(2, Color.Plum, Color.PaleVioletRed);

for (int i = 0; i < 15; i++)
{
    Console.WriteLineAlternating("cats", alternator);
}

Alternate Between 2 or More Colors Based on Number of Console Writes

Alternate Between 2 or More Colors Based on 1 or More Regular Expressions

ColorAlternatorFactory alternatorFactory = new ColorAlternatorFactory();
ColorAlternator alternator = alternatorFactory.GetAlternator(new[] { "hiss", "m[a-z]+w" }, Color.Plum, Color.PaleVioletRed);

for (int i = 0; i < 15; i++)
{
    string catMessage = "cats";

    if (i % 3 == 0)
    {
        catMessage = meowVariant[meowCounter++];
    }
    else if (i % 10 == 0)
    {
        catMessage = "hiss";
    }

    Console.WriteLineAlternating(catMessage, alternator);
}

Style Specific Regions of Text

StyleSheet styleSheet = new StyleSheet(Color.White);
styleSheet.AddStyle("rain[a-z]*", Color.MediumSlateBlue);

Console.WriteLineStyled(storyAboutRain, styleSheet);

    {
        if (unstyledInput[matchLocation.End] == '.')
        {
            return "marshmallows";
        }
        else
        {
            return "s'mores";

Convert Text to ASCII Art Using a Default Font

int DA = 244;
int V = 212;
int ID = 255;
for (int i = 0; i < 3; i++)
{
    Console.WriteAscii("HASSELHOFF", Color.FromArgb(DA, V, ID));

    DA -= 18;
    V -= 36;
}

Convert Text to ASCII Art Using FIGlet Fonts

FigletFont font = FigletFont.Load("chunky.flf");
Figlet figlet = new Figlet(font);

Console.WriteLine(figlet.ToAscii("Belvedere"), ColorTranslator.FromHtml("#8AFFEF"));
Console.WriteLine(figlet.ToAscii("ice"), ColorTranslator.FromHtml("#FAD6FF"));
Console.WriteLine(figlet.ToAscii("cream."), ColorTranslator.FromHtml("#B8DBFF"));

Style Collections With a Gradient

List<char> chars = new List<char>()
{
    'r', 'e', 'x', 's', 'z', 'q', 'j', 'w', 't', 'a', 'b', 'c', 'l', 'm',
    'r', 'e', 'x', 's', 'z', 'q', 'j', 'w', 't', 'a', 'b', 'c', 'l', 'm',
    'r', 'e', 'x', 's', 'z', 'q', 'j', 'w', 't', 'a', 'b', 'c', 'l', 'm',
    'r', 'e', 'x', 's', 'z', 'q', 'j', 'w', 't', 'a', 'b', 'c', 'l', 'm'
};
Console.WriteWithGradient(chars, Color.Yellow, Color.Fuchsia, 14);

Usage Notes

Console colors can be set back to their defaults using the Colorful.Console.ReplaceAllColorsWithDefaults function.

Individual colors in the console's color palette can be replaced using the Colorful.Console.ReplaceColor function.

Colorful.Console can only write to the console in 16 different colors (including the black that's used as the console's background, by default!) in a single console session. This is a limitation of the Windows console itself (ref: MSDN), and it's one that we weren't able to work our way around. If you know of a workaround, let us know!
