Next we'll add highlights and shading to the window frames and blue house trim.
Zoom in very close - 500% or more. As you look closely at windows, you may notice some missing pixels between the shutters and window frames. Copy a strip of white siding and paste in to fill that spot.
Load OUTLINE selection from alpha channel. Hide marquee.
Window Shutters
Tip: Speed things up by completing window & shutters on left, then copy/paste the entire window over the window on right.
Paint outline of shutters and window box the darkest shade of blue from swatch.
Invert the selection and use the lightest blue to add highlights to the window shutters with a 1 pixel line along the top and left side of each section of shutter. (refer to close-up)
Use the third shade of blue (third from left) to add a cast shadow under the cross bars of the shutters.
Window Frames
Invert selection again so outlines are selected.
Paint window frame outline the same way we did the door frame, with a highlight on 'sunlit' side and darker on 'shadow' side. (Refer to close-up.) Use the second lightest brown for the 'sunlit' parts and paint the outside top & left, inside right & bottom.
Paint the remaining window outline with darkest brown - outer right, outer bottom, inner top, inner left.
Round Window
The round window is a little trickier, but it's highlighted the same way.For the round window, paint the OUTSIDE LEFT and INSIDE RIGHT outline the second lightest brown. With the darkest brown paint the OUTSIDE RIGHT outline and INSIDE LEFT outline.
I think this window needs a little more embellishment. Let's add blue trim to this window.
Invert selection marquee.
Using the darkest blue from swatch, paint a row of pixels framing just the left side of window. Follow the same 3-2-1 curve pattern as the brown line (refer to close-up).
Using the lightest blue, paint a row of pixels framing the rest of the window.
De-select the marquee.
Using medium blue (third from left), paint a border around window.
Add a little more substance to this trim by painting a another row of medium blue around window.
Add an accent at the 4 compass points N-S-E-W by painting a third line of medium blue JUST at those 4 points (refer to close-up).
Go around the window frame once more with highlights & shadows. With the darkest blue, paint a row of pixels framing just the RIGHT side of window. With the lightest blue, paint a row of pixels framing the rest of the window.
