Has anyone noticed this about the Tega Sword?

Hypothetical spoilers ahead.

Was watching a quick Instagram reel where they displayed the first ring set in the Tega Sword where this caught my eye.

When you insert a particular ring in the Tega Sword the back palm will glow a particular colour, for both King other it's red, for boonboomger it's Blue, Ryusoulger is yellow and Zyuranger is green.

The reason why this stood out to me is for two reasons 1: We obviously know that Hoeru will take the King other ring probably by the end of the next episode, which he will use in his own arsenal. 2: We know Gozyu Leon will be the (primary at least) user of the Boonboomger ring from previous promotional materials.

This all together leads me to present the hypothesis that whatever colour the back palm of the Tega Sword is when a particular ring is inserted directly correlates with which Gozyuger will be it's owner/primary user.

As it stands then, The King ohger and Don bro rings will got to Hoeru, whilst Boonboomger goes to Leon, Ryusoulger going to Tyranno and Zyuranger going to eagle. From what I've seen there is not ring that lights the Tega Sword black or at least not yet.

What you all think of this?
