may help you . As the comments say you can store the 32-bit ARGB value. It's basically a numeric value. If you code this way then there won't be any need to write a function to extract the color value.
'your string selected from a color dialog
Dim clrDialog As New ColorDialog
If clrDialog.ShowDialog = Windows.Forms.DialogResult.OK Then
        TextBox1.Text = clrDialog.Color.ToArgb.ToString 
End If
clrDialog.Dispose()

' to get back ARGB value from string
TextBox1.BackColor = Color.FromArgb(CInt(TextBox1.Text))

Convert a color from the Color class into a human readable String

hope this fix your issue Get use of Java reflection. This code gives useful output. You can remove unwanted ones from ArrayList via something like list.remove("BITMASK");
import java.awt.Color;
import java.lang.reflect.Field;
import java.util.ArrayList;

public class Test
{
    public static void main ( String [] args )
    {
        Field [] names = Color.class.getFields();
        ArrayList < String > list = new ArrayList < String >();

        for ( Field name: names )
            list.add( name.getName() );
        for ( int i = 0; i < list.size(); i++ )
            System.out.println( list.get( i ) );
    }
}

Convert hexadecimal color to string (for color blind programmers)

wish of those help The easiest way is to find the nearest color in a table, e.g. X11. Distance is simply (abs(Red1-Red2)+abs(Green1-Green2)+abs(Blue1-Blue2))

How to convert Flutter color to string and back to a color

I hope this helps . In Dart the as operator doesn't allow you to change the actual structure of an Object, it just allows you to provide a hint that an object might have a more specific type. For example, if you had a dog and an animal class you could use as to specify that your animal is actually a dog (as long as the object is actually a dog).
class Animal {}
class Dog extends Animal {}

Animal animal = new Dog();
Dog bob = animal as Dog; // works, since animal is actually a dog
Animal animal2 = new Animal();
Dog bob2 = animal2 as Dog; // fails, since animal2 is actually an Animal
Color color = new Color(0x12345678);
String colorString = color.toString(); // Color(0x12345678)
String valueString = colorString.split('(0x')[1].split(')')[0]; // kind of hacky..
int value = int.parse(valueString, radix: 16);
Color otherColor = new Color(value);

Flutter/Dart: Convert HEX color string to Color?

Any of those help Our database has colors saved as a String like "#AABBCC" and so I'm basically looking for a function like this: Color.parseColor("#AABBCC"); for Flutter
/// Construct a color from a hex code string, of the format #RRGGBB.
Color hexToColor(String code) {
  return new Color(int.parse(code.substring(1, 7), radix: 16) + 0xFF000000);
}

How can I convert an RGB color to a KML hexadecimal color string?


Tag : matlab , By : Robert MacGregor
Date : March 29 2020, 07:55 AM
fixed the issue. Will look into that further The built-in colormaps in MATLAB will give you matrices of RGB color triples that are scaled from 0 (lowest intensity) to 1 (highest intensity). To convert a single RGB triple to its KML color style equivalent (with the AABBGGRR format), the steps are:
Scale it from 0 to 255. Flip the order to BGR. Add a transparency value to the beginning (0 for fully transparent, 255 for fully opaque). Convert to a uint8 type to ensure you have integers in the range 0 to 255. Convert to hexdecimal strings using dec2hex. Reshape the result into a 1-by-8 array of characters.
>> color = [1 1 0];  % The RGB triple for yellow
>> hexColor = reshape(dec2hex(uint8([255 255.*flip(color, 2)])).', 1, 8)

hexColor =

FF00FFFF
>> N = 10;        % Number of colors
>> map = jet(N);  % 10-by-3 jet colormap
>> hexMap = reshape(dec2hex(uint8([255.*ones(N, 1) 255.*flip(map, 2)]).').', 8, []).'

hexMap =

FFAA0000
FFFF0000
FFFF5500
FFFFAA00
FFFFFF00
FFAAFF55
FF55FFAA
FF00FFFF
FF00AAFF
FF0055FF
