Hi, first of all let me tell you that I already have an greyish Indian Ringneck which is a female, and so I'm planning to buy a second one (male) because i'm in college and i don't have much free time to play with so i think buying her a friend will probably be a good choice, and according to the Pet Shop which is near my street where i live they currently have three indian ringnecks (untame) for sale, exactly as you can see from the picture below, they told me that the blue one is a male, you can see that it has more squarer head than others, and I will buy it, but I'm not sure if it is dark blue or light blue, so please tell me what mutation excatly is, can you find any photo on Google to show me how he can be when it grows to 2-3 years because he now is only 5 months old, thank you!
