Coming from a black and white world, Cross can't help but marvel at Color's colorful figure

You can see it as a queer platonic or romantic relationship (even though "romance" is mentioned on the card, that part can be ignored).

Some headcanons about them!

As soon as Cross arrives in the OmegaTimeline, Color offers to help Cross adapt to this new universe, already having experience with similar processes after helping one of Killer's versions adjust to this peaceful timeline.

Even though his trust issues brought a lot of conflicts — especially due to Cross's aggressive and almost violent personality — Color managed to get close to him almost instantly, and Cross couldn’t help but get attached to the skeleton.

In the confession part, Color knew from the start that Cross had a puppy crush on him — and although it was mutual, Color knew that it was Cross who should confess, in order to strengthen a little bit of his trust.

Even though Cross is taller than Color, Cross prefers to be the little spoon because he wants to be protected while he sleeps — and Color's arms always make him too relaxed to stay alert.
