Lesson one in growing: Stop, don't panic, everything is going to be okay...probably! Your little plant is all new and fresh and that's just how they look when they're new and fresh! Just like babies, when plants are this small, the parents (growers) haven't had a chance to screw them up yet. Your plant is only suffering from one thing: it's young so it's a bit paler green than what you may have envisioned.
You'll notice, as your plant continues to grow, that the new growth tends to be a little lighter in color than the more mature leaves. All plants do this and it's perfectly normal. Your plant looks healthy for where it is so you can rest easy!
