1. Yellow at the front door is a bold entrance choice, but goes well with the modern exterior like wood paneled bright brick blocks with grey or black trims of the windows and door. And the same paneled wood pattern or texture paint you can keep for interior along with furniture in natural or artificial wooden paint colours.
2. To update the exterior of a traditional home like modern ones, choose the garage shade for door colour paint and to define the exterior, keep window panels large and open. To add more width to the house look, install the LEDs which throw light horizontally and choose a neutral colour like grey or stone grey for external walls. For internal walls also, stick to the same colour and keep the colour of furniture black or dull white as it will accentuate the character of the house.
3. If you want to have a timeless door colour paint on your front door that tunes well with light, medium, as well as dark colours, try egg blue. It looks amazing at the door with dark exteriors like grey and charcoal and blends well with light and neutral interior. To pair up egg blue with the décor and furnishings use white and the faded shades of linen and drapes and the same for sculptures, vase, frames and trims.
