I decided I was tired of garbage iPhone photos and bought a used Canon Rebel XSI... by no means a top of the line camera I know, but something I could afford and learn with. I have read stickies and info about some of the basics, took some notes and got started when my new camera arrived. But I'm having an issue with photos looking so washed out its as if they are in black and white. See the images below... the first one is on full automatic settings. The second two are when I tried to do the settings myself, and you'll see what I mean about the colors being washed out. PS- I know the first two are a little out of focus, I need to get a tripod, but that's not my main concern at the moment...
I'm shooting with the stock 18-55 mm lens. I use aperture priority mode on f/9.o. On this mode shutter speed should select automatically from what I understand. I also use autofocus, auto white balance (tried changing that too and had similar issues with all preset modes), and image stabilizer. I haven't messed with ISO, but my understanding was that ISO only makes the photos more or less clear/grainy, and shouldn't change the color?
So then I thought maybe I can fix in post-processing, but no luck so far (admittedly I have only used Photoshop express editor so far... can I fix these in full photoshop?)
So, what am I doing wrong? I would love any feedback you can offer to help me learn!

. The only recommendations I'll make to get you in the ballpark is a tripod (must have) and using your lens manual focus instead of the autofocus and learn to shoot in RAW format instead of .jpg
