-====== Description ======
-The **color_alpha** texture property combines the **[[gamedev:textureproperties:color|color]]** and the **[[gamedev:textureproperties:transparency|transparency]]** texture properties in one texture property. Sometimes it is useful and saves disk space if the alpha channel of an image or color is used directly as the transparency value.
-The red, green and blue components (component 0, 1 and 2) are used exactly the same way as in the **[[gamedev:textureproperties:color|color]]** texture property. The alpha component (component 3) is used exactly as in the **[[gamedev:textureproperties:transparency|transparency]]** texture property. See the appropriate texture properties to learn the details.
-If the **color_alpha** texture property is defined together with the **[[gamedev:textureproperties:color|color]]** and/or the **[[gamedev:textureproperties:transparency|transparency]]** texture property the **color_alpha** texture property is applied first then the other texture properties.
-The color values are typically an 8 bit image with 4 color components with the data of all color components located inside the range from 0 to 1. 0 represents 0% light reflectivity (respectively 0% opaqueness) for a color component while 1 represents a 100% light reflectivity (respectively 100% opaqueness). Values outside this range are physically not plausible.
-The default value for this texture property is opaque pure black (0, 0, 0, 1).
