Texture Editing Help

[Mister_Haudrauf]

Could Someone change this Eitrigg.blp texture to have White Hair like the Blademaster or the White Hair Paladin. It should mostly look the same but he should have white hair. I don't know how to do White hair.
And if someone ask this is a mixture of the Grunt (Entire Body), ChaosOrcRange (Head) and Blademaster (Botton Right: Ear). Just made gray.
