Give her gifts every day. I suggest gems, flowers, or apple pie.
There is no Orange Heart Event. Muffy only has a Black, Purple, Blue, and Yellow Heart Event.
I believe she likes flowers, so give her a flower every day.
3pm to 5pm
Muffy's black heart event is at the Blue Bar from 3PM to 5PM. She pretty much asks you what type of girls you like. Answer, "Cheerful and pretty" and she'll be happy.
Give her wine (call up the supermarket on your phone and you can buy for 300g) everyday and her heart will go up quite quickly.
Walk from main path to Goddess Pond at 3:40 pm to 6:00 pm, not Monday
You can do it anyway, even if you do already have moo milk because of I managed to do it so...hope that kind of helped!

Muffy's Blue heart event is Blue Heart Event » Blue Bar » 6:00 pm to 8:00 pm, not Wednesday It may not work if you missed a heart event or you didn't follow those requirements.
It's green THEN yellow
Are you making sure you are doing these two things? » Blue Bar » 3:00 pm to 5:00 pm ?
Make sure you've done her other three events. Then check to see if you are going at the right time. Here is what you have to do to activate her Yellow Heart Event: Yellow Heart Event » Blue Bar » 4:00 pm to 6:00 pm, not Wednesday » Celia has a yellow, orange, or red heart color » You have seen the black, purple, and blue heart events
