Hey @Charul192, thanks for raising the PR. For the announcement bar, we are looking to use a light orange background. Could you please update it to a lighter shade of orange?

[Charul192]

Hi @Achanandhi-M,
I’ve updated the announcement bar with a lighter orange shade as requested. The color now aligns better with the Keploy logo and looks balanced in both light and dark mode.
Please review it whenever you get a chance. Thank you!

Hey @Charul192,
We need the default light orange background color. Could you please update it throughout the full design? Also please fix the DCO and prettify issues

Hey @Charul192 Still the pipelines are failing, can you please fix it, don't try to fix the vale linter issues, try to fix the other pipeline issues, also in your PR why there are 61 files are changed?

[Charul192]

Hey @Achanandhi-M,
I have tried to fix all the failing pipelines.
Kindly review it.

Hey @Charul192 i think again the pipelines are failing, we want the very light orange color not a dark orange color and it needs to be good in the dark mode also
