RT#1022 Glow-in-the-dark picture

Request Tracker in action. I hope K likes the result.

Nice to finally get some use out of these luminous paints. Really the biggest drawback with them has been that the red glows only very briefly (the green and white last longest), and that they dry white, not clear, in daylight.

Also nice to find a use for one those colour-changing-LED butterflies I had picked up in a bargain shop for no good reason.

Make a glow-in-the-dark picture for K. Maybe a small black canvas with glowing paint for a flower, grass, stars etc, so it looks all black in the daytime. An LED butterfly with just the LED and clear parts on the visible side of the canvas would probably look good.

The paints glow under UV light (checked with the blacklight) and fluoresce a little after the light is off too. Maybe use some UV LEDs round the edge of the canvas

UV LEDs are quite expensive and may or may not work:

  Q) Is this product suitable for making UV paint flourese (glow) from a distance of 10 meters? Thanlks Meat-Head

  A) No sorry this product does not support that.


Instead, have glass painted the butterfly (badly). It turns out the glow-in-the-dark paints dry white, not clear, so that's going to be awkward.

Since the butterfly sticks out so much I thought I'd make more of the picture 3D.

Have started a gerbera daisy shape built from lolly sticks and toothpick bits, centred on the hole the butterfly LED section comes through.

Waiting for the PVA to dry.

Looks pretty bad so far, maybe it will be better painted.

Not sure what to do for the background / rest of canvas, maybe out-of-focus field of flowers.

Looks OK painted. Went round the edges in glow green. Background is out-of-focus flower field. Made the mistake of mixing glow colour with background; had to overpaint sky to stop it swamping the picture. Grass is still swamping the flowers a little when glowing.

Need to replace the LED in the butterfly with either white (dimmed) or red.

Not replacing the LED on the grounds that it probably won't get turned on much, if at all.

Sky overpainting seems to have done the trick.

Up on K's wall in a spot she chose.
