chore(colors): tweak colors to match latest values for SHINE

[mukunku]

Summary

Some colors needed tweaking so this PR updates our colors to the latest values defined in the Figma designs.

How to Test

No easy way to test this change besides spot checking a few colors and comparing them to what we have in code vs. what's in the Figma designs.

Here are the latest colors from color-sets.less in table form for easy viewing: https://docs.google.com/spreadsheets/d/1bemMtdwnJKRs0uIM9dfT5507r-cXxQKtE5MEC_vGd_U/edit?gid=0#gid=0

Light HC mode looks correct.

Dark HC needs a change for:

• yellow-300 #E5D17E (it's different than regular Dark)
• green-300 #C4E589 (very minor tweak)
• green-400 #CCE5A1 (very minor tweak)
• orange-300 #DFAD90
• orange-400 #fcccb1
• blue-300 #A6C4FF

• A6C4FF

Looks like Figma is rounding the HSV/HSBA values which is causing the discrepancy. By converting your Hex values to HSV/HSBA myself I was able to accurate represent the colors as you mentioned: f99f8fa

Update: https://stackexchange.slack.com/archives/C096063B1PH/p1765209444766689
We decided to not use fractionals so we're keeping the values as they were.

I spot checked a color from each set and they all matched up to the variables in figma. Thanks @mukunku!
