Balancing The Color Pallette In Our Front Tulips

A couple of weeks ago, I posted some photos of the newly bloomed tulips that came up in our front yard bed right in front of the large Maple tree.  Go see that photo here.  They look - to me at least - to be orange and red.  I say that because the reds were *supposed* to be pink, but they came out much more like a true red.  They looked great.  Or at least I thought they did.  That was, until I came across this ebook from Pretty Purple Door.  It is called "7 questions to ask yourself to choose the right plants for your garden" and you can get it by giving her your name and email address here on her site.  I'm not going to link directly to the .pdf because she is running a biz, but I do want to show one little nugget that is in that guide.  She talks about color palette and then lists a few of her favorites and a few to avoid.  To be respectful, here's a screenshot, but I've blurred out the parts that aren't relevant here.  (Again...if you want the full guide, go here.)

First, let's look in the center column.  Avoid these combinations, she says:

Huh...orange and pink.  Welp....that's kinda what we have.

But...look in the left column.  See what she says there?  Add yellow and you take a red/orange combo to a red/orange/yellow combination and that becomes one of her favorites.

So, how do we make this set of tulips right?  I think by adding yellow this Fall.   I don't have this on my To-Do List addendum, but I'm thinking that I now need to revisit that post and add a few items.   Now on the list?  Buy yellow Tulip bulbs this fall.  And next Spring, it will look something like this:
