I can have item named but it can always be white.So how can I make some name to other color?

I believe that the answer is to add the getRarity(ItemStack) method in your class that extends Item. I recommend that you also look at EnumRarity to find the rarity, or item name's color, that you want.

You could also use escape characters, an example is below.

\247~COLOURVALUE~

i made a tutorial for this a while back. i'm not an expert at java nor am i an expert at modding but i think i did a good job with the tutorial.

 

LanguageRegistry.addName(DragonSword, "\u00a7~ Item Name");  replace the ~ with the color code.

 

for more info including the color codes you can check my basic tutorial here http://darkhaxspace.weebly.com/colored-text.html

 

 

hope it helps
