Hi,

Just update you class same like below class. 
public class MyClass 
{
    class RGB 
    {
        Integer red;
        Integer green;
        Integer blue;
        RGB(Integer red, Integer green, Integer blue)
        { 
            this.red = red;
            this.green = green;
            this.blue = blue; 
            system.debug('this is red :' + red);
        }
    }
    
static Map<String, RGB> colorMap = new Map<String, RGB>();
static 
{
    colorMap.put('red', new RGB(255, 0, 0));
    colorMap.put('cyan', new RGB(0, 255, 255));
    colorMap.put('magenta', new RGB(255, 0, 255)); 
}

  public MyClass()
  {
        system.debug( 'this is the static colormap : ' + colorMap);
  }

}

Please follow below step :-

Step 1) Click on Your Name then click on Developer console.
Step 2) In developer console click on Debug and open Anonymous window like below or click

Step 3) Enter below code in Anonymous window like below
MyClass obj = new MyClass();

Step 4) Click on Open log check box and click on execute like above screen shot.
Step 5) Then search your debug like below "this is the static colormap"

I tested above code in my developer org which is working fine. Please let us know if this will help you

Hi Arav,

Please check the below modified code:
  
public class MyClass {
    class RGB {
        Integer red;
        //system.debug('this is red :' + red);
        Integer green;
        Integer blue;
        //Static and Instance Methods, Variables, and Initialization Code
        //Classes, Objects, and Interfaces
        RGB(Integer red, Integer green, Integer blue)
        //system.debug(this is RGB : + RGB);
        { this.red = red;
        this.green = green;
        this.blue = blue; }
    }
    static Map<String, RGB> colorMap = new Map<String, RGB>();
    //system.debug('this is the static colormap : '+ colorMap);
    static {
        colorMap.put('red', new RGB(255, 0, 0));
        colorMap.put('cyan', new RGB(0, 255, 255));
        colorMap.put('magenta', new RGB(255, 0, 255)); 
    }
}

The above class is saving it properly. But I would recommend to follow below links to learn about Apex Programming.

https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/

https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_intro_what_is_apex.htm

https://developer.salesforce.com/page/Apex

https://developer.salesforce.com/page/An_Introduction_to_Apex

https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_intro_learning_apex.htm

Please do let me know if it helps you.

I found below issue in your code
1) Debug system outside the constructor and method
2) No ' ' in Debug Statement

Please update  your class like below 
public class MyClass 
{
    class RGB 
    {
        Integer red;
        Integer green;
        Integer blue;
        RGB(Integer red, Integer green, Integer blue)
        { 
            this.red = red;
            this.green = green;
            this.blue = blue; 
            system.debug('this is red :' + red);
        }
    }
    
static Map<String, RGB> colorMap = new Map<String, RGB>();
static 
{
    colorMap.put('red', new RGB(255, 0, 0));
    colorMap.put('cyan', new RGB(0, 255, 255));
    colorMap.put('magenta', new RGB(255, 0, 255)); 
}

  public MyClass()
  {
        system.debug( 'this is the static colormap : ' + colorMap);
  }

}

To excute above class try below code on developer console 
MyClass obj = new MyClass();
Output will :- 
36.0 APEX_CODE,DEBUG
Execute Anonymous: MyClass obj = new MyClass();
23:41:20.32 (32783658)|EXECUTION_STARTED

Hi Arav,

First save this class in Salesforce UI:
  
public class MyClass {
    class RGB {
        Integer red;
        Integer green;
        Integer blue;
        //Static and Instance Methods, Variables, and Initialization Code
        //Classes, Objects, and Interfaces
        RGB(Integer red, Integer green, Integer blue) { 
			this.red = red;
			this.green = green;
			this.blue = blue; 
		}
    }
	
    static Map<String, RGB> colorMap = new Map<String, RGB>();
    static {
        colorMap.put('red', new RGB(255, 0, 0));
        colorMap.put('cyan', new RGB(0, 255, 255));
        colorMap.put('magenta', new RGB(255, 0, 255)); 
    }
    public MyClass() {
        System.debug('===colorMap:'+colorMap);
    }
}

Go to Developer Console and create an object for the parent class:

MyClass mc = new MyClass();

This way it will work properly. Also don't forget to enable the debug so that it will be easy for you to see the output.

static Map<String, RGB> colorMap = new Map<String, RGB>();
static 
{
    colorMap.put('red', new RGB(255, 0, 0));
    colorMap.put('cyan', new RGB(0, 255, 255));
