Ok, Im new to blender and yafray and i made this.
The letters should be white but they are not I use the Full mode of yafray with one light above the scene and an energy of about 14. Why are the colors so blue? I hope I posted this to the right place.
Thanks.
For the blue writing im guessing either the lamp is blue or you are using a sky sphere which might be blue or sumthing like that.
Also to get a better picture using yafray you need to increase the Antialiasing samples which will get rid of the jagged edges.
