How do I change the colour on customers login page?

Hello,

I recently upgraded and purchased a new template. Long story short, one of my customer reached out and said that the buttons on her login page are hard to see. The buttons background is white and the text is a light yellow. 

I use this same exact shade of yellow in different parts on my website but I don't want it on this particular button  - its not even noticeable. I tried everything but I'm still unable to fix it. I am using the honey theme. I would be great if someone can help me.

Hello @featherbeautifu 

Hope you are doing well

For color related changes, I will need your shopify URL to guide.

Also I suggest to try this app which can helpful for your customers to login into your store very easily
