Need to change tick box colour for T’s and C’s etc for Ocean + Woocommerce

Hi there, I need to change the customer check box ticks to a colour, but can’t find any access to this. My website background is white, as is the tick, so you can’t see it’s been ticked at all- it’s on the ‘deliver to different address, T
s and C’s, and also, I need to change the stripe and paypal selection buttons to a colour too (separate issue, but same reason) I hope someone can help?
