Okay, Green and yellow together are popping too much , even if its a personal choice go for one of these colours (yellow or green) and preferably lighter shades. The red colour on the left also looks too off and can be avoided. Too much mustard in base makes it look dull. What you can do is go for more grey/white as base colour,mustard as filler and brown/dark grey as a bold colour and a yellow/green as popping colour as highligter. Some observations that you might try for the elevation. 1.Do not go for more than 4 colours 2.Try keeping your boundary wall to not merge too much with the house.(Especially the center part base and boundary wall) 3.Lighter colours on horizontally prominent areas(for example the base) and bold colors on vertical elements(for example the element on your right side that is in white color). 4. The central brown element with window can be made better with grooves in different color like brown with gold strip and giving the base a single color (that abrupt green is looking weird). For example, imagine that element in grey on white base or vice verca. You can also explore cladding materials in market for that center and get some good antique/stone or modern jaali finish as per your personal choice. 5.The Jaali on left is white and the base visible behind is also a light colour.Try to go for dark and light combination(either base dark or jaali, suggesting to keep base light and jaali dark so that sun shadows created patterns are visible).
