Thelymitra aff. ixioides, one of NZ’s two spotted blue sun orchids, requires a hot sunny morning after rain for 2 or 3 ±18mm wide flowers to open for a few hours only, typical of self pollinated species. The Aussie T. ixioides opens more flowers more easily for insect pollination. This specimen from low tea-tree scrub in poor soil at Hewett’s Reserve west of Whangarei on 9/10/02. Found from Cape Reinga to Christchurch in similar conditions and track sides.

If you look at this orchid through the red/cyan anaglyph goggles, the colour will look just as poor as on the anaglyph. The red anthers will lose their colour. Poor quality goggles which are too pale may actually show red better, at the expense of poor channel separation and more ghosting. That is because more red sneaks through the pale cyan filter and it is only the right eye which is differentiating colour in an anaglyph.
The left eye (red) just sees black and white.
