I changed impulse theme background color to black . As a result, I changed the border and line colors to white, but the arrow in the variant selector does not appear. I would appreciate it if you could tell me how to resolve this issue. You can provide me with CSS code to fix the issue Thank you for any help you can provide.
Store URL: Lightup.design
Product page URL: Lightup.design/collections/best-selling/products/acrylic-letters
Thank you in advance 
I check your product it seems like the arrow icons on that area is not properly set up. I take time to look for it then this is what ive found.
The one that you have in there is only a pciture/image, it just add in the background. So when you change the background in all pages this background picture on the selector also gone.
The icons must have HTML code and CSS code.
I hope it help.

Thank you so much @Made4uo-Ribe . Yes, it was a SVG file. With the help of Photoshop, I changed it to white, uploaded it to Shopify, and finally changed the URL.
So it works. Once again thank you so much
