The scarlet color of the beast rising from the Grave or abyss may denote its rage, reflecting the great anger of the dragon after it is hurled down from heaven and causes a mortal wound to the head of the beast.
(Mt 27:27-28) “. . .Then the soldiers of the governor took Jesus into the governor’s palace and gathered the whole body of troops together to him. 28 And disrobing him, they draped him with a
scarlet cloak. . .”
Being that scarlet is the color of royalty, the scarlet color on the beast more readily identifies the risen beast as
now being the 8th King of prophecy. This seems more in line with what the scarlet color denotes in the scripture.
(Quote from former article) That being the case, so is the ascension of the two-horned beast. The beast rising up from the earth symbolizes the beast returning from the grave – the abyss – coinciding with the seemingly slaughtered head coming back to life.
Although your interpretation could be right in what the earth symbolizes in that scripture, it could also be looked at from another perspective that is interpreted from the bible regarding what earthly means.
(Jas 3:15) “. . .This is not the wisdom that comes down from above, but is the earthly, animal, demonic.”
This interpretation can also be just as valid regarding what earthly means in Rev 13:11-12.
I understand you firmly believe the wild beast that rises from the abyss, the 8th king, and the two horned beast(false prophet) to be one in the same. Yet, you do have certain things that must be reconciled before this can be determined as true. Regardless of your perspective, you must acknowledge that the two are clearly presented as being two distinct entities.
(Re 13:11-12) “. . .And I saw another wild beast ascending out of the earth, and it had two horns like a lamb, but it began speaking as a dragon. 12 And it exercises all the authority of the first wild beast in its sight.. . .”
(Re 19:20) “. . .And the wild beast was caught, and along with it the false prophet that performed in front of it the signs with which he misled those who received the mark of the wild beast and those who render worship to its image. While still alive, they both were hurled into the fiery lake that burns with sulphur.”
