Learn to give a surface its base color with the Albedo channel.
Albedo and color
Albedo represents the pure base color of a surface without embedded direct light or shadow. It reflects the inherent pigment and pattern of the object.
// Setting material Albedo base color to red
mat.color = Color.red;The Albedo channel can receive a solid tint color or be mapped with a detailed 2D image Texture.
Texture tinting
When a Texture2D image is mapped to Albedo, the selected tint color multiplies with the texture pixels. Pure white leaves the image unaltered, while other colors tint it.
// Shifting tint color to blue via code
mat.SetColor("_Color", Color.blue);This mechanism allows deriving mossy green or volcanic red variations from a single neutral stone texture.
Practice Print channel and color info
Assign "Albedo" to channel and "Blue" to color. Print Channel: Albedo | Color: Blue to the console.
Starter code
using System;
class Program
{
static void Main()
{
// channel ve color değerlerini tanımlayıp yazdır
}
}Sample solution
using System;
class Program
{
static void Main()
{
string channel = "Albedo";
string color = "Blue";
Console.WriteLine("Channel: " + channel + " | Color: " + color);
}
}Expected output
Channel: Albedo | Color: Blue

1 Which channel in a material stores pure base color or main texture devoid of lighting and shadows?
- Occlusion
- Emission
- Tessellation
- Albedo Correct answer
Explanation: Albedo is the channel storing the pure base color and primary texture of a surface in PBR material workflows.
2 Set material color
material.____ = Color.green;material.color = Color.green;Explanation: In Unity, the 'color' property is used to alter the main Albedo color of a material.
