The Problem:
I am trying to customize the DeepSeek UI to visually replicate the ChatGPT interface. However, I have encountered a significant rendering discrepancy.
When I set a specific color (e.g., #9da7b2) for backgrounds or accents in both ChatGPT's and DeepSeek's customization settings, the perceived visual result is completely different.
Setting the exact same HEX code does not produce the same color on screen. This indicates that the underlying CSS rendering (such as alpha channels, background blending, CSS color-mix, or base layer opacities) is calculated differently in DeepSeek compared to ChatGPT.
The Request:
My specific ask is this: I want DeepSeek's "Customization Settings" to have a dedicated preset (e.g., "ChatGPT Dark/Light Theme") or an improved rendering logic that makes the output visually identical to ChatGPT.
Specifically, if I input #9da7b2, I want the visual result on my screen to be exactly the same shade as it looks in the official ChatGPT web interface. I don't want to just match the HEX number in the input box; I want the final visual output to be indistinguishable.
What I have already tried:
I have attempted to manually tweak the HEX codes to compensate for this difference, but the opacity and blending behaviors make it nearly impossible to match perfectly just by guessing the HEX values.
Attached :
Screenshot 1: DeepSeek customizer with HEX #9da7b2.
Screenshot 2: ChatGPT interface with the same HEX #9da7b2 (showing the visual difference).
