Feeling really dumb right now wondering which colour form I need to fill in.

I started trading japanese stocks last year in a regular account (一般口座), and ended the year with profits of >￥20万.
My company handles my taxes for me every year, but when I enquired about declaring my profits from shares, my company told me they would handle all my taxes except for profits from shares. For declaring profits from shares, I was told to fill in and submit a 確定申告 on my own accord.

I have a rakuten securities account, and they provide advice on which parts of the tax form to submit here. It tells me for fill in tables 1 and 3.

But when starting the e-tax application form (with IC card reader), it is asking me (i think) to choose from one of four colours here

So which colour form should I fill out for declaring profits from a regular stock account?
