Lighter color to shed more light on the topic and spike positivity

I like the lighter cover in optoin A

I chose A because i feel that the lighter color green pops more and looks better than the other one.

The lighter colors is more eye-catching. I think this would stand out more than the other one on the shelf

The lighter green feels more appropriate for the title.

The dark green lettering stands out against the light green background and compliments the subject matter better.

The light color makes the book look less like a textbook and more like a friendly indestructible.

Both are a little plain, but I like Option B better. Option A looks more like some sort of academic journal, or something really, really dry. Option B looks more accessible and readable.

I like the darker green cover seen in option B as it is more reminiscent of plants than the mint green color in option A. I think the white title stands out better against the dark background as well.

I think this color and style emphasize the end product the book aims to help with better; that is, healthy green plants.

Option B's color scheme is more appealing visually compared to option A

i like this shade of green over option a's

The darker cover is better representative of the title in my opinion

I like the deep green for this topic. I would suggest making the letters more whiter to stand out a bit more.

Color is green with leaves, matches title/topic
