My SaaS landing page colors aren't getting the right emotional response, what am I doing wrong?

hi everyone, super new to this whole marketing psychology thing. i'm really struggling with my SaaS landing page – the colors just aren't hitting right, and conversions are kinda stagnant. it's pretty frustrating!

we've built a new AI-powered project management tool, and teh goal for our landing page is to convey innovation, reliability, and ease of use. i want visitors to feel confident and excited about using it, like 'this is the future of productivity!'.

i did some basic research on color theory, you know, the usual 'blue for trust' stuff. so, for trust and professionalism, I went with a lot of blues and greys. for 'innovation' i tried a subtle accent of a brighter teal. I thought this palette would invoke a good emotional response for a productivity tool, but it seems like i might've missed the mark.

it feels like the colors are either too bland, or maybe they're sending the wrong signals. i've even had a few early testers mention it feels 'too corporate' or 'a bit boring,' which is the opposite of what i want for an innovative tool. i expected a feeling of calm efficiency, but it's more like... indifference. the desired emotional response just isn't there.

i ran a quick, unscientific poll asking for initial feelings, and the results were kinda all over the place. here's a snippet of a fake 'user sentiment log' to show the unexpected reactions:

USER_SENTIMENT_LOG:
[
  {"user_id": "U001", "feedback": "looks reliable but kinda dull", "emotional_response": "neutral"},
  {"user_id": "U002", "feedback": "professional, but where's the 'wow'?", "emotional_response": "unimpressed"},
  {"user_id": "U003", "feedback": "feels like a bank website, not a tech startup", "emotional_response": "bored"},
  {"user_id": "U004", "feedback": "safe choice, but doesn't excite me", "emotional_response": "indifferent"}
]

so, my main questions are:

• how do you properly research and apply color psychology for a SaaS landing page, especially when trying to evoke a specific emotional response like 'innovative trust'?
• are there common mistakes beginners make when picking colors for tech products?
• what tools or methods do you use to test if your chosen color palette is actually having the desired psychological effect on your audience?

has anyone here faced similar struggles trying to get their landing page colors to resonate?
