right you see the colours at the bottom left of the screen well they are premixed gradients so 2 speak.just above where you are you should see two options one should say colour swatchs which you are on the other should say colour mixer.

Click on the one that says colour mixer if you havent chosen a gradient then now is you time either go back to swatchs and get it or go to the drop down menue on the colour mixer part and choose either radiel or linier.

Now below you there is a line and it should have two little points one at either end you can move these around too change the affect on your colour.

To change the colour of one of these you click on it and then select a coulour from the little pad above the line.

You can have more than two of these little points ( i forget what they are called lol) by click somewhere on the line you can then move it and change the colour to something of your choise.

Any more questions post another reply.

cheers rusty
