How to Set the Color of a Material in Unity's Shader Graph Using Hexadecimal Values

When working on game development with Unity, you might find yourself needing to adjust the colors of materials to match your desired aesthetic or theme. One of the common methods you may want to use for specifying colors is hexadecimal values. In this guide, we’ll discuss how to set the color of a material in Unity's shader graph using these hexadecimal values.

Understanding the Problem

The real challenge arises when you want to set a material's color using a hexadecimal value. This can be especially tricky if you are new to Unity or to programming in C# . However, the good news is that it’s quite straightforward once you get the hang of it.

Setting the Color of a Material

Step 1: Accessing the Material

To set the color of a material, you'll first need to obtain a reference to the MeshRenderer component of the game object. Here is a basic example to demonstrate this:

In this example:

mat is a public variable you can assign in the Unity editor.

SetColor function specifies which color property is being set ("Color_B10F9E01") and assigns it a color value in hexadecimal format ("3F7232").

Step 2: Converting Hexadecimal to Color

However, the above example won't work directly because Unity requires color values in a different format. Instead of passing a string for the color, you should use the Color32 structure. Here’s how you can do it:

Breakdown of the Code

new Color32(r, g, b, a): This constructor takes four parameters:

r (Red - 0 to 255)

g (Green - 0 to 255)

b (Blue - 0 to 255)

a (Alpha - 0 to 255)

Each of these values represents one channel of color. The hexadecimal color code is broken down into pairs of two for each color channel.

Example Walkthrough

The hexadecimal color # 3F7232 corresponds to:

Red: 3F in hexadecimal = 63 in decimal

Green: 72 in hexadecimal = 114 in decimal

Blue: 32 in hexadecimal = 50 in decimal

Alpha: Typically fully opaque, we can use 0xFF (255 in decimal).

So, the equivalent Color32 would be:

Conclusion

Setting the color of a material in Unity's shader graph using hexadecimal values can be done easily by converting the hex colors into the Color32 structure format. By following the steps outlined in this guide, you can ensure that your materials have the right colors and enhance the overall visuals of your game.

Experiment with different hexadecimal values to create vibrant effects that will surely boost the aesthetics of your work!
