Texturepack questions

Thanks. In videos I've seen damage recoloured.

If anyone else can be more descriptive about any of this that would be much appreciated. Still not quite sure what I should name the redstone gradient folder (btw does a gradient folder mean like water.png, grasscolour.png and foliagecolour.png?) and how big the enchantment overlay is and what to call it (enchantment_overlay.png? I don't think it reads spaces and I don't know where it is located anyway) or what size the folder with the menu buttons should be, and in what format.

Shiny_UnderpantsI have a few questions related to texturepacks. If any of you can answer please do. If any of you have questions too feel free to ask them.
The questions:
1) how do you change the colouring of redstone in a texturepack?
2) how do you change the colouring of dye in a texturepack?
3) how do you change the colouring of enchantments in a texturepack?
4) how do you change what the menu looks like in a texturepack?
5) how do you change the colouring of damage in a texturepack? (when you take damage you flash red briefly.)

Thanks.

1. Through a gradient .png I'm not sure of the name.
2. You can just recolour each block/item.
3. Enchantment overlay .png
4. title folder should hold what you require, the buttons are in the gui folder, and the fluid background is done in another folder too I believe
5. Not sure if you can do this.
