In a large bowl, mix Greek yogurt, garlic paste, ginger paste, red Kashmiri chilli powder, cumin powder, garam masala, tandoori masala, food colouring, and salt.
Add the cubed chicken and mix well, ensuring all pieces are coated. Marinate for at least 1 hour (overnight for best results).
Preheat the grill or oven to medium-high heat.
Thread the marinated chicken onto skewers and brush with melted butter.
Cook for 12-15 minutes, turning occasionally, until charred and fully cooked.
Brush with additional melted butter and garnish with fresh coriander.
