Color not always seems to present the required colors
Yes, it is true, I also acquired a Libra Color. It was given to me by my loving spouse who wanted to put an end at my hesitation whether to buy one or not. Oh well, worse things happen
Anyway, this puts me in a perfect position to check the colorfulness of the device and I did some strange discoveries after putting some seemingly perfectly formed epubs from my Libra 2 (I still will use that) on the Libra Color. The first finding (see attachments) was that a colored "dropcap" did not showed. The used original style found in the epub: Code:
span.dropcap1 { font-size: 1.75em; font-weight: bold; color: Red; } .special { font-family: sans-serif; } Code:
<p><span class="dropcap1"><span class="special">“W</span></span>hat the—”</p> Code:
span.dropcap2 { font-family: sans-serif; font-size: 1.75em; font-weight: bold; color: Red; } Code:
<p><span class="dropcap2">“W</span>hat the—”</p> Did anyone have similar findings? PS: Kepub-yfing the epub by just adding ".kepub.epub" did made both text variants show in red, while "links" now are grey-ish with an underline even while the style setting did specified text-decoration: none;.

Is rainbow mode on or off? The nearly 300 dpi mode isn't compatible with colour and colour mode really only allows 150 dpi.
It could be there is some kind of automatic decision to render in mono (for a a poorer than mono eink) 300 dpi, or to render in 150 dpi for colour content. TBH, I expect this. |

Rainbow is OFF. See also my added comment in the original posting: it seems an rendering issue as the results from an EPUB is different from an KEPUB.
There is also a new finding: when kepub-yfing an EPUB2, I get a warning that the stylus is not usable, while kepub-yfiing an EPUB3 does not trigger that warning. Last edited by DrChiper; 06-12-2024 at 09:57 AM. |

The stylus is useless for epubs anyway for serious proof/annotations. On Sage I'd only have used it on PDFs (or notebooks), but I don't use the stylus at all now.
What difference does rainbow on/off make to skinny italics? I might create some test files. I don't use kepub at all now. Even bought Kobo ebooks are downloaded to PC. I did originally because I didn't understand the Extended driver on my H2O original. Last edited by Quoth; 06-12-2024 at 11:24 AM. |

For the moment I did found a possible solution (=workaround): Code:

No clue, never tried yet. Too advanced for the moment Same goes for all devmod settings which are useless without an proper explanation. Of course I can assume, but assuming is deadly and to be avoided. Me too. I just use them as reference to see whether they do something better/differently compared with my standard EPUBs. |

I did some color tests and found the following results (see attachment KLC screenshot).
Mark the missing color last column, 4th entry from bottom. That was supposed to be "rebeccapurple", but seems to be not displayable on the KLC, it is in the calibre viewer and other devices. Last edited by DrChiper; 06-15-2024 at 02:05 PM. |

A screenshot though is misleading compared to a photo of the screen.
It's odd that a screenshot doesn't do "true colour", i.e. 24 bit RGB, 8 bits per R, G and B. Some mono Kobos certainly did when I checked years ago. |

For what it may be worth, I see the same thing. Rebeccapurple does not work but #663399 does work. This has been reported to Kobo.
Code:
<td style="background-color:rebeccapurple;color:white;" title="rebeccapurple = #663399"> rebeccapurple </td> </tr> Code:
<td style="background-color:#663399;color:white;" title="rebeccapurple = #663399"> rebeccapurple </td> </tr> Last edited by DNSB; 06-12-2024 at 03:57 PM. |

I too have spent a fair amount of time reading about css, html, etc. I had already edited a few stylesheets identical to your code below without success. Various hex equivalents have not been recognized either. It must be something I am not doing but haven't a clue what that may be.

I have a worse confession! I've never used "color names". I just put the RrGgBb hex and if in doubt occasionally use a colour picker gadget to see the hex code. |
