Talk:Attribute clash

Screenshots needed
This page could badly use some screenshots to show the effect... when I get chance I will add some.

high-res sub-char dynamic color changes
It would be great to see things like the "Nether Earth" radar and (although not strictly attribute clash circumvention, but a similar technique nevertheless) the sky/sand separation on the border of "Ugh!" nicely integrated in this article. BACbKA 00:21, 31 December 2005 (UTC)

Wikified and screenshotted
I've added a few pictive examples as well as a bit of wikification. It's by no means perfect, but anyone can mess around with the screenshots now to create something resembling an article. Jamyskis Whisper, Contribs 01:01, 16 January 2006 (UTC)


 * As well as correcting some factual errors from your contributions, I've removed the frame rate comment about Altered Beast: because the Spectrum had a small graphics memory, you don't need much memory bandwidth to update the screen. If you have a source for this, please cite it and revert. Cheers --Pak21 23:08, 16 January 2006 (UTC)

reference to Shock demo by ESI
ESI's Shock was definitely not the first program to use the more-than-two-colours-per-cell trick. It even appears in some games (e.g. title screen of Black Lamp and possibly the border of Aquaplane) though (as far as I know) not during any arcade-style game because the precision of timing required would leave too little time for the game's own processing. So perhaps somebody could find a better example. —The preceding unsigned comment was added by 86.131.90.68 (talk • contribs).

Why Spectrum-centric?
I don't understand why this article mainly focuses on Spectrum. Attribute clash was an artefact present in every home computer of the time. And the statement -- "Most notably, Sinclair ZX Spectrum" -- aside from lack of any references, it's not true in countries where ZX did not sell, which is everywhere except UK. One could say "most notably, the Apple II" since the Apple's adjacent-pixel-colour scheme lead to more atrocious attribute clash than most (just look up a 1980's game on Mobygames and compare screenshots of Apple to anything else.) As a matter of fact the term could be extended to include any computer output device -- eg. on a VT220 terminal, printing single-height chars on a line set to double-height would cause an attribute clash. --Jquarry (talk) 22:22, 20 January 2008 (UTC)

The term "color clash" was coined associated with the zx spectrum in "sinclair" magazines. The effect could be present in any other machines (not really) but as far as I can remember it's term is heavely related to zx spectrum. --87.103.2.156 (talk) 17:52, 14 May 2009 (UTC)

Image copyright problem with Image:Knight lore 3.gif
The image Image:Knight lore 3.gif is used in this article under a claim of fair use, but it does not have an adequate explanation for why it meets the requirements for such images when used here. In particular, for each page the image is used on, it must have an explanation linking to that page which explains why it needs to be used on that page. Please check


 * That there is a non-free use rationale on the image's description page for the use in this article.
 * That this article is linked to from the image description page.

The following images also have this problem:

Color -> Colour
I propose to Euro this article, given that the primary topic surrounds the ZX Spectrum, and the MSX line of computers - both of which had a greater European (and Japanese) following than they did in the US.

The main change would be color -> colour, but there may be other changes as well. Seems to me that wp:engvar is appropriate. a_man_alone (talk) 17:13, 4 November 2011 (UTC)

Demo scene link leads to a wrong target
The reference to "demo scene" is linked to the "Game demo" article that talks about demo versions of computer games. "Demo scene" means a completely different thing. Apparently a link to the "Demoscene" article was intended. 173.11.122.193 (talk) 01:00, 17 October 2014 (UTC)

The TMS9918A and the 8x1 colour block
The TMS9918A Video Display Processor hasn't got the same attribute clash of the ZX Spectrum. In fact, it hasn't the limit of 2 colours for a 8x8 pixels block but instead for a 8x1 pixels block. The TM9918A supports 2 colours for each byte of colour memory, and since 1 byte of colour memory stores the colour attributes for 1 byte of pattern memory, and since 1 byte of pattern memory stores info for 8 pixels in graphics 2, the limit is 2 colours per single line of 8 pixels. In fact, in the example image of the article, you can clearly see that the foreground colour is changed only through horizontal lines. --Leo72 (talk) 08:41, 4 April 2021 (UTC)
