Visual Images...What do they mean?

I chose to look at the image "La Guernica". As far as color goes, the use of dark pigments says something to me as the reader/interpreter. The dark colors at the top do not align with the thought of Bang, that states that freedom, happiness and triumph are placed at the top of the images. I think that the only peaceful image at the top is the object that looks like a light...maybe this was supposed top be representative of nearing the end of a bad time. On the other hand, some of the images, like the bull, and the people are distorted and abstract looking. The overall piece seems to be broken, and sad. Maybe this was to show the feelings of the people living during this period?? I also think that the jagged edge of the sword is countered by all of the rounded images, which leave me feeling a little less on edge about it all. I think that the size of the image also plays an important role because it shows that this was a meaningful event in time. I think that Bang was right in some sense, the larger the image is the more powerful it can be. I think that this painting is full of ways in which it can be interpreted. I know I only scratched the surface...
