Red, Green, Blue and Alpha lines are referring to colour channels. Depending on your colour profile, all digital images include different colour channels within their information, the most used profile (and the one we are using) is RGB, also called RGBa. You can visualize those colour channels in editing programs such as GIMP and Photoshop.

Normal map, Mask, Vertex Color/Alpha and UV2 columns are the textures / 3D you can edit for your model:

• Normal map is the blue-purple texture. It’s a bump map giving information about heights and depth on your surface and how light should refract on it.
• Mask is the green-blue texture. This map is giving the information about the reflectivity of the face, the roughness (or glossiness) and the refraction of the light withing the model. (sub-surface-scattering)

You can edit those 2 textures with editing programs such as GIMP or Photoshop.

• Vertex color and Vertex alpha (also called Color attributes) are colours assigned in your model’s 3D. These will define which part of the model will be painted with or without the second iris colour. (heterochromia)
