+# Changing the color of the triangle
+
+As we have seen, the color of the triangle is hard coded in the pixel shader. It is possible to pass the color we want to the pixel shader, and we will do like the pixel coordinates. We need to modify the C code and the shader code. Here are the steps for the C code:
+
+* Add the four components of the BGRA color in the `Vertex` structure:
+
+```c
+typedef struct
+{
+ UINT x;
+ UINT y;
+ BYTE r;
+ BYTE g;
+ BYTE b;
+ BYTE a;
+} Vertex;
+```
