In a room, there is a chest called the "Chameleon Chest," which changes its appearance to match the color of the clothing of the person who last touched it. Currently, it is blue, matching the shirt of Kofi, who is the last person to have touched it. There are three people in the room: Kofi, who is colorblind; Leena, who is wearing a red dress; and Takeshi, who wears a green jacket and is not aware of the chest's magical property. Leena is aware of the chest's property and tells Takeshi to touch the chest without revealing the reason. What color will the chest appear to Kofi, Leena, and Takeshi after Takeshi touches it? Provide a brief response.
When Takeshi touches the Chameleon Chest, it changes its appearance to match the color of Takeshi's green jacket. 

To Leena, the chest will now appear green, because she can see colors normally and knows about the magical property of the chest. She expects this change, and it matches her understanding of the chest's ability.

For Takeshi, the chest will also appear green; however, he might be surprised by the sudden change. As he was not told about the chest's magical property, he will not understand why the chest changed color but will see it as green nonetheless.

Kofi, being colorblind, may have difficulty distinguishing certain colors, depending on the type of colorblindness he has. Since the chest was blue before and it is now green, if Kofi has a common type of red-green colorblindness, he might not be able to distinguish the change depending on the specific shades involved. Therefore, Kofi might still perceive the chest to be the same color as before the chest changed, or he might see it as another color entirely, depending on his unique perception of the color spectrum and the specific nature of his colorblindness. However, he will not perceive it as green specifically, as he is colorblind.
