Analyse Textures first pixel

Is there a way i can store the first pixel in an image texture to a variable? How would I analyse it?

Use GetPixel to get any pixel in a texture. (Unity - Scripting API: Texture2D.GetPixel)

Texture2D texture;
Color color=texture.GetPixel(0, 0);

Each pixel is a color value and you can analyze it as such.
