L'arc-en-ciel des couleurs

Article posté par Johndizro

Partout présentes, intimement liées à la lumière qu'elles manifestent, nous les voyons, ou plutôt, de la lumière nous ne voyons que les couleurs. N'est-ce pas dans la diffraction d'un rayon de soleil qu'apparaissent les sept couleurs du prisme qui s'ordonnent selon leur longueur d'onde : rouge, orange, jaune, vert, bleu, indigo, violet ? Quand on joue avec un prisme en absence de rayon lumineux, deux nouvelles couleurs apparaissent : turquoise et magenta. Dans l'industrie, les couleurs du spectre de la lumière sont un peu différentes : rouge magenta ou pourpre, rouge, jaune, vert, bleu cyan et bleu foncé.
Les couleurs peuvent être lumières (faisceaux lumineux) ou matières (support tangible matériel, un pétale de fleur par exemple). Elles obéissent à des lois différentes mais complémentaires. Par exemple, les couleurs lumières sont soustractives et leur superposition donne la lumière blanche (introduction du blanc), les couleurs matières sont additives, leur superposition tend vers le noir.
La couleur est un langage. Des qualités, des fonctions sont attribuées à chaque couleur, et ce dans tous les domaines de la vie (science, art, religion).
A titre d'exemple : le rouge dans le plan biologique active le développement des plantes, l'orange favorise la sérénité des moines bouddhistes, le jaune stimule le mental, le vert de la nature régénère, le bleu est une couleur apaisante, le violet favorise l'intériorisation et la méditation.
L'arc-en-ciel est l'arche d'alliance, le lien entre l'invisible et le visible, l'intangible et le tangible, c'est aussi l'escalier de sept marches que le Bouddha "illuminé" redescend. Le chiffre sept est un archétype, un sujet d'étude passionnant (sept jours dans la semaine, sept glandes endocrines, sept chakras majeurs [centres énergétiques des Orientaux, ils auraient dans le corps énergétique une fonction analogue à celle des glandes endocrines dans le métabolisme de notre corps], sept notes de musique dans la gamme, etc.).
Le glissement du chiffre sept au chiffre six se fait insensiblement : sept couleurs pour trois couleurs primaires et trois couleurs secondaires ; sept jours dans la semaine mais six jours de travail pour un de repos ; sept astres visibles de la terre dans le système solaire, six planètes et une étoile, le soleil ; sept notes dans la gamme de musique mais six tons qui les séparent.smiley sg3agbigeekg3ag.gif
