Star Colors

For Famous planets I'm trying to create a red giant.
I'm using the color parameters but I'm not getting the desired results
The picture here has orangeColor defined as the star color. But IMO it's not orange but more like yellow.
I also used redColor and it's not exactly the deep red I'm after.

These are the current settings in my .plist:

Any ideas?

Code: Select all

1 109" =//Edsodi
{
texture="Edsodi.png";
corona_flare = 0.80; // from 0.0 to 1.0
corona_hues = 0.45;    // from 0.0 to 1.0
corona_shimmer = 0.7;
sun_color=orangeColor;

"description" = "The red giant star Oberon tells the sad story of Edsodi, a planet burnt almost to a cinder. During the day people live underground as Oberon literally burns the surface. Nightlife is everything on this very hot planet and is as exotic as a fairytale. The fantastic light coming from the multicolored glowworms on the roofs of Mexpator the capital city is unforgettable. Access for landing ships is through a four hundred metre deep crater, ships are advised to approach the planet on the dark side and land during local night time. The mass and instability of the star Oberon is the main cause of the frequent earthquakes.";

Don't know much about the technicalities, but that comes out orange (or sort of peach) on my computer.

I think you cannot create a red giant. All suns have white as their basic colour, which is shaded in a reddish, or blueish, or yellowish, etc. way.

I guess sun_color only allows you to modify the white, not to replace it with a completely different colour. The clue may be in the

Why not make it a blue supergiant star, then most of the story would still work (obviously change the colour of the star)?

mm so dark red is not possible? :cry:

I know blue giants are perfectly possible. But I want a red giant :evil:
:wink:

Is there not possible to implement a parameter like

discColor= "redColor"
?

Can you post a screenshot?
Does it look much different from my screenshot?

El Viejo posted a screenshot with a star. I mean to get this corona color.
But I though redColor would give me that.

I think you misunderstood. In your screenshot the star has an orangey peach colour on my laptop screen but not deep red as you seek. Never been to that system in Oolite myself (I tend to end up testing and playing around with OXP's rather than playing the game so have never made it to galaxy 2 in Oolite) But be warned, my laptop has this auto brightness thing that has fooled me before.

Looking in the code I see that the sun colour is always blended with 50% whiteColour. So your guess is right. I updated the wiki with this info.

Thnx for explaining. So if I understand it correctly there is no way to control this white-blending?

Code: Select all

corona_flare = 0.4; // from 0.0 to 1.0
corona_hues = 0.4;    // from 0.0 to 1.0
corona_shimmer =0.0;
sun_color=greenColor;
yes green color.. and yes it seems stupid that in order to show a red corona, we need to emit a green light..

that should change..

Hi Frame,

Strange,

Green looks green on my monitor and the Corona is displaying correctly?

Code: Select all

"1 109" =//Edsodi
{
texture="Edsodi.png";
corona_flare = 0.60; // from 0.0 to 1.0
corona_hues = 1.0;    // from 0.0 to 1.0
corona_shimmer = 0.4;
sun_color=greenColor;

"description" = "The red giant star Oberon tells the sad story of Edsodi, a planet burnt almost to a cinder. During the day people live underground as Oberon literally burns the surface.

};
Now I'm puzzled
:shock:

EDIT BTW: I like this color so I leave this system in this way :)
