Change colour of guiTexture from green to red.

Question

I have a heath bar as guiTexture with green colour, which scales down as per the available health.

     //health is updated like so
     health = health/100f;
 
     //healthBar is updated like so
     rect = healthBar.pixelInset;
     rect.width = originalWidth*health;
     healthBar.pixelInset = rect;

This works fine.

How to change it's colour as well according to available health?

e.g. 100% health - green colour, 50% health - green to red colour less than 10% health - red colour

I have tried with,

 Color.Lerp(Color.green, Color.red, health - 1);

But I am not familiar with Color.Lerp;

You can set a GUITexture's color using 'GUITexture.color'. I believe that color is an overlay, so you'll want your bar texture to be white. Color.Lerp() takes a value between 0 and 1 for the last parameter, so your code might be:

 guiTexture.color = Color.Lerp(Color.red, Color.green, health);

This assumes that health goes from 1.0 (healthy) to 0.0 (dead?).

This directly changes to Red colour. I am reducing health by -0.1.

You need to pass values between 0.0 and 1.0. Post the code you are using.
