Yes. In graphic novels, 'le bleu est une couleur chaude' can be a very unique concept. It goes against the common perception that blue is a cold color. This might be used in a graphic novel to create a special atmosphere or to convey a different kind of emotion. For example, the artist might use blue in a way that gives a feeling of warmth and passion, which is different from how we usually view blue.
One way is through the use of lighting. If a scene in a graphic novel has a blue - tinted light that is also associated with positive and warm emotions like love or hope, it can show that blue is a warm color in that context. Also, characters dressed in blue can be shown in situations where they are sources of warmth, like a blue - clad hero saving the day and bringing comfort to the people.
