Colours Don't Work Properly. Can We Fix This?

[Welding-Torch]

• Briefly describe the bug Ans: I am building in app with a small colour coding system. While building it, by experimentation I found that Tkinter Designer cannot 1:1 reproduce colours as they are in Figma. Below I have attached 2 screenshots; one from Figma(Expectation) and one from after build(Result).
• Operating System Ans: Windows 10 2023 h1
• What is the expected behavior? Ans: 1:1 Colour Reproduction - Please provide step by step instructions on how to reproduce the bug Ans: The colours that don't work are E464D7 (Pink) and E46464 (Coral)

UPDATE:

I did some more testing and, this bug doesn't have to do with the colours being reproducible.

The only difference between rectangles with working colours and rectangle that show only black is the "Smoothening of the Corners". See the below examples to understand

Corner Smoothing - Leads to Black Rectangle

Independant Corners - Leads to Colorful Rectangle
