I have seen that style done before. Reminds me of how the sorts of sites that have free game downloads with japanese/chinese elements used to look before they took up darker tones.
It's worth learning what the impact of color choices, both in the realm of how the mind works and how art chooses to use that.
In psychology, colors can evoke gut reaction responses, such as the combination of red and yellow increasing appetite (notice how much fast food uses those colors), while blue is seen as generally unappetizing beyond association with the food itself (blue ketchup for example had very poor sales). Yellow increases tension, blue calms, and red is intense for how it is the first place in a picture your eye will be drawn to.
In art, complementary colors are when you pair it's opposites. When one is warm and the other is cool, it can create an illusiory sense of depth, causing the warmer color choice to have more "pop". Supplementary colors meanwhile are those next to eachother on the color wheel, which itself makes for a design that is easier on the eyes from the hue gradation.
Color theory is used all over the place to attempt to control the eyes and minds of users, be it art, clothing, web design, T-shirt design, etc. What "looks good" can work up to a point, but it's subject to our own eyes alone. Some people for example might love Comic Sans, but that does not mean it looks good in a business sense.
I like art, I like psychology, and color goes through both areas.
Combining the two turns art from cool aesthetics into a form of manipulation. It helps me both be less prone to falling for it, and more able to use it to my advantage.
I may have also written a rather long thesis on the topic of how art can control the minds of the viewer when I was still at college, paired with a presentation that was mostly designed to show those things through example. It also went into focal point theories and your own eye's motions caused from within the source, alongside the power that comes with it from making the elements within form a triangle of focus that doesn't leave the frame, causing it to minorly entrap the spectator's gaze.
It manipulates it's viewers. A splash of color on a tiny canvas, a simple piece of audio, a strong scent, this is all capable of being called art, and you can cause entire masses of people to feel something without a direct context in their own lives to achieve it.
Art can be dangerous for what it can elicit from it's spectators. Much of the Nazi's success came from the focus on television's power on the masses, which is basically art capable of being distributed on a wide scale, alongside the use of propaganda within the art itself (go figure, Hitler was first an artist).
It's not just some doodles on paper, art is manipulation.
