Well, I'd like to explain my thought process on this resprite, and I'd like to explain a few things.
1. There very much should've been a feedback thread, but it's already merged so I'll keep that in mind for the future. (also no idea Resi was working on this either)
2. Visual clarity, I.E, does it look like what it's supposed to do? / Ease of Gameplay
For starters, the color. It's purple on white. Science colors. It looks like it belongs in Science, not Medical.
To illustrate, which one of these is not like the other? Yeah, the hypospray.
(yeah, but what about Zeng-hu? Fine, whatever. There can be a purple motif, but it can't take up more like 50% of the color.
Right now if you've stripped literally everything with the description and name it literally looks like a gun SCIENCE could pull out of the protolathe!)
Let's jump into the shoes of CargoTech McBaldie. He's sorting out crates and he takes one look at it. "Oh, it's purple! It's clearly science stuff."
"GEE, I WONDER WHICH DEPARTMENT THIS BELONGS TO."
That's what I'm trying to avoid here. I mean, not everyone has sunk a 100 hours playing medical and know every surgical tool and chem like the back of their hand. I know, because I have.
Visual consistency ( Looking in line with everyone else )
Look, I didn't pull out this design out of my ass. I'm trying to make the tools look visually similar together.
3. The words
Literally the description states, "Air-needle", I.E, there's no needle. It uses AIR to inject the stuff.
And there's a needle on it. The literal reason why we're using hyposprays is to avoid the filthy needle cross-contamination and having to use a new syringe every time.
4. Foreword
Look, I'm willing to compromise here, hell, add a purple light-up attachment or something. Because I will definitely not approve a full revert.
