Blue flowers and red filaments

 

Blueweed

 

The Viper's Bugloss (Echium vulgare) produces a lot of rich nectar, a blue pollen, and attracts pollinators.  It looks great, but, should be avoided.

Echium vulgare

  

The prickly hairs can be skin irritants. The plant contains pyrrolizidine alkaloids; these can cause liver damage to livestock and humans. The alkaloid is also in the honey.  The honey should not eaten regularly or for long terms.

Security envelope marbled

 

Marbled

This envelope security pattern is more intricate than it looks.  The blue marbling is printed over a grey pattern.  This is done to add an extra layer of security.

 

 

 

Beachy day

It's a beach!

Blue with white stripes, or white with blue - this umbrella is at the beach for the day.

Security envelope polygons 2

Unlike the polygon security envelope pattern previously posted here,

 

Blue polygons

 

this polygon pattern does not seem to want to be mirrored and matched to create a bigger pattern.  Despite that hinderance, it is an interesting pattern.  

 

N.B. this pattern came from an envelope used by the same business that used the previously posted polygon pattern.

 

Addendum:  by doing a V flip and an overlay, it is possible to extend the pattern slightly in the vertical; nothing seems to inspire a further extension in the horizontal or vertical.

 

 

Just a flip and overlay

 

Maybe one of the readers can provide a way to extend this pattern?

Security envelope blue diamonds

This envelope security pattern features diamonds on blue paper.

Those are tilted squares

The registration markers can be seen in the upper corners of the wings.

Security envelope polygons

Security envelope patterns come in different patterns.  Usually, they are small and tightly packed, covering the whole interior of the envelope to obfuscate the contents.  It was a pleasant surprise to receive this envelope security pattern of widely spaced polygons.

 

It's a tee shirt!

This blue polygon pattern has been mirrored left-right and  up-down.  The tiny diamond in the center is the lower-right, lower-left, upper-right, and upper-left corner, respectively, of the pattern after the horizontal and vertical flipping and tiling.

Some sketchy V and H flips and overlays give a rough draft view of a more complete polygon security pattern.

 

. . . flipped and overlaid . . .

 

This rough sketch demonstrates the result of enthusiastic polygon pattern and line matching.

 

adjusting lines to meet

 

It is possible to continue the process and create even denser patterns.

Pre-school school

Prior to opening

A stroll past a school building before the school year has started allows for a leisurely view of the sky reflected in the windows.

A swipe of light yellow brightens up this study of sky blue on grey.

The security coils glisten in the sunlight.

 

 

 

Blue wall

A chair from the 1950s

A dark blue wall, white trim, a black vinyl upholstered chair with chrome legs, and a lighter shade of blue - maybe someone will sit in that chair when it gets shady?

Building on blue

A blue sky, a blue building...

Building "en bleu"
