Change background color of input fields (need 3 colors for use case)

I've searched and see that you can change the color of ALL of the input background fields.  I have a use case where I need 3 different colors for the input fields on ONE page:  #1. Normal for most fields.   #2. Blue background for "male" fields. #3. Pink background for "female" fields.   This is for a nonprofit agency that provides resources to low income families, but we need to capture 4 numbers from each family (Number of Male Adults, Number of Male Children, Number of Female Adults, Number of Female Children) for grant purposes, and was trying to make things more obvious (and redesign the form), because as simple as it sounds, the caseworkers are having trouble with this.  Thx.

Hey there! 

Can you provide a link to the page you are working on and the password if its a protected site? The code solution will depend on the individual form fields names in order to target them for unique colors. Thanks!

Thanks so much, I am grateful for you taking a look at it.  I have not begun to revamp it, I'm trying to see what is possible (hence the question) and work with the caseworkers to see what makes sense.   Here is the link to the current page, I'll PM you the password:   https://fullyfurnishedministries.org/request

I didn't build the original, but am also thinking of ideas to make the form shorter/more intuitive/easier to complete, so any suggestions are welcome! 

Oof I am struggling with this one! @tuanphan is a legend, maybe he can help you? 

The code for stylizing all input fields, or even input fields of a certain type (text, number etc) is easy peasy but this is a little trickier. 

upon inspection each individual form field input is a yui not a block-yui which means we cant target them individually that way. I was messing around with targeting the whole form and narrowing it down by using the :nth-child selector but I'm unable to get it to act the way I want it to. 

Good luck and Ill be excited to see when someone finds a solve. 

OK thanks @FluffCreativeStudio for the follow up and time spent.   Thanks for mentioning @tuanphan and will watch for input from them.

What is access password?
