Steps used to create Cool Bytes logo in InkScape

Canvas Size

• Open a blank document in InkScape.
• Go to File -> Document Properties and select Display tab.
• Change the Width to 250 and Height to 200 of the Canvas.

Block Shape

• Select Polygon with 4 corners and use CTRL+SHIFT to create a Rhombus shaped block.
• Convert the block to path by selecting Path -> Object to Path
• In order to get rounded corners, select Path -> Path Effects.
• In the window that's opened, click + and search for Corners and add it.
• Use the Nodes tool and select 2 of the adjacent corners of the square to make the corners rounded.
• Clone the square 3 times, but make one of the rounded corners of one of the squares as sharp.
• Use rotation tool to rotate the squares.

Layer 1 (Actual Colored Squares)

• Add following colors to each square:
  • Blue (Top Square) - #2d618cff
  • Green (Left Square) - #3d9970ff
  • Red (Right Square) - #8c3636ff
• Add a circle at the intersection, with the color: #ffd343ff
• Group the blocks into a single object for easy movement.

Layer 2 (White Background Squares)

You can try using Path -> Linked Offset but it requires a little more effort, since this doesn't work on grouped objects.

• Create white squares similar to colored ones but with a little higher size, so that it's visible behind the colored square.
• Use exact same process as colored ones, such as corners, grouping etc.
• Use colored blocks to refine border radius and border width.

Layer 3 (Shadow Squares)

• Clone Layer 2 group and change a few settings:
  • Change Color to Black
  • Change Blur to 15%
  • Change Opacity to 50%
